Listen: we know homework isn’t fun, but it is a good way to reinforce the ideas and concepts you’ve learned in class. But what if you’re really struggling with your homework assignments? 

If you’ve looked online for a little extra help with your take-home assignments, you’ve probably stumbled across websites claiming to provide the homework help and answers students need to succeed . But can homework help sites really make a difference? And if so, which are the best homework help websites you can use? 

Below, we answer these questions and more about homework help websites–free and paid. We’ll go over: 

  • The basics of homework help websites 
  • The cost of homework help websites 
  • The five best homework websites out there 
  • The pros and cons of using these websites for homework help 
  • The line between “learning” and “cheating” when using online homework help 
  • Tips for getting the most out of a homework help website

So let’s get started!

The Basics About Homework Help Websites–Free and Paid

Homework help websites are designed to help you complete your homework assignments, plain and simple. 

What Makes a Homework Help Site Worth Using

Most of the best sites allow users to ask questions and then provide an answer (or multiple possible answers) and explanation in seconds. In some instances, you can even send a photo of a particular assignment or problem instead of typing the whole thing out! 

Homework help sites also offer more than just help answering homework questions. Common services provided are Q&A with experts, educational videos, lectures, practice tests and quizzes, learning modules, math solving tools, and proofreading help. Homework help sites can also provide textbook solutions (i.e. answers to problems in tons of different textbooks your school might be using), one-on-one tutoring, and peer-to-peer platforms that allow you to discuss subjects you’re learning about with your fellow students. 

And best of all, nearly all of them offer their services 24/7, including tutoring! 

What You Should Should Look Out For

When it comes to homework help, there are lots–and we mean lots –of scam sites out there willing to prey on desperate students. Before you sign up for any service, make sure you read reviews to ensure you’re working with a legitimate company. 

A word to the wise: the more a company advertises help that veers into the territory of cheating, the more likely it is to be a scam. The best homework help websites are going to help you learn the concepts you’ll need to successfully complete your homework on your own. (We’ll go over the difference between “homework help” and “cheating” a little later!) 

body-gold-piggy-bank-money

You don't need a golden piggy bank to use homework help websites. Some provide low or no cost help for students like you!

How Expensive Are the Best Homework Help Websites?

First of all, just because a homework help site costs money doesn’t mean it’s a good service. Likewise, just because a homework help website is free doesn’t mean the help isn’t high quality. To find the best websites, you have to take a close look at the quality and types of information they provide! 

When it comes to paid homework help services, the prices vary pretty widely depending on the amount of services you want to subscribe to. Subscriptions can cost anywhere from $2 to $150 dollars per month, with the most expensive services offering several hours of one-on-one tutoring with a subject expert per month.

The 5 Best Homework Help Websites 

So, what is the best homework help website you can use? The answer is that it depends on what you need help with. 

The best homework help websites are the ones that are reliable and help you learn the material. They don’t just provide answers to homework questions–they actually help you learn the material. 

That’s why we’ve broken down our favorite websites into categories based on who they’re best for . For instance, the best website for people struggling with math might not work for someone who needs a little extra help with science, and vice versa. 

Keep reading to find the best homework help website for you! 

Best Free Homework Help Site: Khan Academy

  • Price: Free!
  • Best for: Practicing tough material 

Not only is Khan Academy free, but it’s full of information and can be personalized to suit your needs. When you set up your account , you choose which courses you need to study, and Khan Academy sets up a personal dashboard of instructional videos, practice exercises, and quizzes –with both correct and incorrect answer explanations–so you can learn at your own pace. 

As an added bonus, it covers more course topics than many other homework help sites, including several AP classes.

Runner Up: Brainly.com offers a free service that allows you to type in questions and get answers and explanations from experts. The downside is that you’re limited to two answers per question and have to watch ads. 

Best Paid Homework Help Site: Chegg

  • Price: $14.95 to $19.95 per month
  • Best for: 24/7 homework assistance  

This service has three main parts . The first is Chegg Study, which includes textbook solutions, Q&A with subject experts, flashcards, video explanations, a math solver, and writing help. The resources are thorough, and reviewers state that Chegg answers homework questions quickly and accurately no matter when you submit them.  

Chegg also offers textbook rentals for students who need access to textbooks outside of their classroom. Finally, Chegg offers Internship and Career Advice for students who are preparing to graduate and may need a little extra help with the transition out of high school. 

Another great feature Chegg provides is a selection of free articles geared towards helping with general life skills, like coping with stress and saving money. Chegg’s learning modules are comprehensive, and they feature solutions to the problems in tons of different textbooks in a wide variety of subjects. 

Runner Up: Bartleby offers basically the same services as Chegg for $14.99 per month. The reason it didn’t rank as the best is based on customer reviews that say user questions aren’t answered quite as quickly on this site as on Chegg. Otherwise, this is also a solid choice!

body-photomath-logo-2

Best Site for Math Homework Help: Photomath

  • Price: Free (or $59.99 per year for premium services) 
  • Best for: Explaining solutions to math problems

This site allows you to t ake a picture of a math problem, and instantly pulls up a step-by-step solution, as well as a detailed explanation of the concept. Photomath also includes animated videos that break down mathematical concepts to help you better understand and remember them. 

The basic service is free, but for an additional fee you can get extra study tools and learn additional strategies for solving common math problems.

Runner Up: KhanAcademy offers in-depth tutorials that cover complex math topics for free, but you won’t get the same tailored help (and answers!) that Photomath offers. 

Best Site for English Homework Help: Princeton Review Academic Tutoring

  • Price: $40 to $153 per month, depending on how many hours of tutoring you want 
  • Best for: Comprehensive and personalized reading and writing help 

While sites like Grammarly and Sparknotes help you by either proofreading what you write via an algorithm or providing book summaries, Princeton Review’s tutors provide in-depth help with vocabulary, literature, essay writing and development, proofreading, and reading comprehension. And unlike other services, you’ll have the chance to work with a real person to get help. 

The best part is that you can get on-demand English (and ESL) tutoring from experts 24/7. That means you can get help whenever you need it, even if you’re pulling an all-nighter! 

This is by far the most expensive homework site on this list, so you’ll need to really think about what you need out of a homework help website before you commit. One added benefit is that the subscription covers over 80 other subjects, including AP classes, which can make it a good value if you need lots of help!  

body-studtypool-logo

Best Site for STEM Homework Help: Studypool

  • Best for: Science homework help
  • Price: Varies; you’ll pay for each question you submit

When it comes to science homework help, there aren’t a ton of great resources out there. The best of the bunch is Studypool, and while it has great reviews, there are some downsides as well. 

Let’s start with the good stuff. Studypool offers an interesting twist on the homework help formula. After you create a free account, you can submit your homework help questions, and tutors will submit bids to answer your questions. You’ll be able to select the tutor–and price point–that works for you, then you’ll pay to have your homework question answered. You can also pay a small fee to access notes, lectures, and other documents that top tutors have uploaded. 

The downside to Studypool is that the pricing is not transparent . There’s no way to plan for how much your homework help will cost, especially if you have lots of questions! Additionally, it’s not clear how tutors are selected, so you’ll need to be cautious when you choose who you’d like to answer your homework questions.

What Are the Pros and Cons of Using Homework Help Sites?

Homework help websites can be a great resource if you’re struggling in a subject, or even if you just want to make sure that you’re really learning and understanding topics and ideas that you’re interested in. But, there are some possible drawbacks if you don’t use these sites responsibly. 

We’ll go over the good–and the not-so-good–aspects of getting online homework help below. 

3 Pros of Using Homework Help Websites 

First, let’s take a look at the benefits. 

#1: Better Grades Beyond Homework

This is a big one! Getting outside help with your studies can improve your understanding of concepts that you’re learning, which translates into better grades when you take tests or write essays. 

Remember: homework is designed to help reinforce the concepts you learned in class. If you just get easy answers without learning the material behind the problems, you may not have the tools you need to be successful on your class exams…or even standardized tests you’ll need to take for college. 

#2: Convenience

One of the main reasons that online homework help is appealing is because it’s flexible and convenient. You don’t have to go to a specific tutoring center while they’re open or stay after school to speak with your teacher. Instead, you can access helpful resources wherever you can access the internet, whenever you need them.

This is especially true if you tend to study at off hours because of your extracurriculars, work schedule, or family obligations. Sites that offer 24/7 tutoring can give you the extra help you need if you can’t access the free resources that are available at your school. 

#3: Variety

Not everyone learns the same way. Maybe you’re more of a visual learner, but your teacher mostly does lectures. Or maybe you learn best by listening and taking notes, but you’re expected to learn something just from reading the textbook . 

One of the best things about online homework help is that it comes in a variety of forms. The best homework help sites offer resources for all types of learners, including videos, practice activities, and even one-on-one discussions with real-life experts. 

This variety can also be a good thing if you just don’t really resonate with the way a concept is being explained (looking at you, math textbooks!).

Not so fast. There are cons to homework help websites, too. Get to know them below!

3 Cons of Using Homework Help Websites 

Now, let’s take a look at the drawbacks of online homework help. 

#1: Unreliable Info

This can be a real problem. In addition to all the really good homework help sites, there are a whole lot of disreputable or unreliable sites out there. The fact of the matter is that some homework help sites don’t necessarily hire people who are experts in the subjects they’re talking about. In those cases, you may not be getting the accurate, up-to-date, and thorough information you need.

Additionally, even the great sites may not be able to answer all of your homework questions. This is especially true if the site uses an algorithm or chatbot to help students…or if you’re enrolled in an advanced or college-level course. In these cases, working with your teacher or school-provided tutors are probably your best option. 

#2: No Clarification

This depends on the service you use, of course. But the majority of them provide free or low-cost help through pre-recorded videos. Watching videos or reading info online can definitely help you with your homework… but you can’t ask questions or get immediate feedback if you need it .

#3: Potential For Scamming 

Like we mentioned earlier, there are a lot of homework help websites out there, and lots of them are scams. The review comments we read covered everything from outdated or wrong information, to misleading claims about the help provided, to not allowing people to cancel their service after signing up. 

No matter which site you choose to use, make sure you research and read reviews before you sign up–especially if it’s a paid service! 

body-cheat-cheating-cc0

When Does “Help” Become “Cheating”?

Admittedly, whether using homework help websites constitutes cheating is a bit of a grey area. For instance, is it “help” when a friend reads your essay for history class and corrects your grammar, or is it “cheating”? The truth is, not everyone agrees on when “help” crosses the line into “cheating .” When in doubt, it can be a good idea to check with your teacher to see what they think about a particular type of help you want to get. 

That said, a general rule of thumb to keep in mind is to make sure that the assignment you turn in for credit is authentically yours . It needs to demonstrate your own thoughts and your own current abilities. Remember: the point of every homework assignment is to 1) help you learn something, and 2) show what you’ve learned. 

So if a service answers questions or writes essays for you, there’s a good chance using it constitutes cheating. 

Here’s an example that might help clarify the difference for you. Brainstorming essay ideas with others or looking online for inspiration is “help” as long as you write the essay yourself. Having someone read it and give you feedback about what you need to change is also help, provided you’re the one that makes the changes later. 

But copying all or part of an essay you find online or having someone write (or rewrite) the whole thing for you would be “cheating.” The same is true for other subjects. Ultimately, if you’re not generating your own work or your own answers, it’s probably cheating.

5 Tips for Finding the Best Homework Help Websites for You

Now that you know some of our favorite homework help websites, free and paid, you can start doing some additional research on your own to decide which services might work best for you! Here are some top tips for choosing a homework help website. 

Tip 1: Decide How You Learn Best 

Before you decide which site or sites you’re going to use for homework help, y ou should figure out what kind of learning style works for you the most. Are you a visual learner? Then choose a site that uses lots of videos to help explain concepts. If you know you learn best by actually doing tasks, choose a site that provides lots of practice exercises.

Tip 2: Determine Which Subjects You Need Help With

Just because a homework help site is good overall doesn’t mean that it’s equally good for every subject. If you only need help in math, choose a site that specializes in that area. But if history is where you’re struggling, a site that specializes in math won’t be much help. So make sure to choose a site that you know provides high-quality help in the areas you need it most. 

Tip 3: Decide How Much One-On-One Help You Need 

This is really about cost-effectiveness. If you learn well on your own by reading and watching videos, a free site like Khan Academy is a good choice. But if you need actual tutoring, or to be able to ask questions and get personalized answers from experts, a paid site that provides that kind of service may be a better option.

Tip 4: Set a Budget 

If you decide you want to go with a paid homework help website, set a budget first . The prices for sites vary wildly, and the cost to use them can add up quick. 

Tip 5: Read the Reviews

Finally, it’s always a good idea to read actual reviews written by the people using these homework sites. You’ll learn the good, the bad, and the ugly of what the users’ experiences have been. This is especially true if you intend to subscribe to a paid service. You’ll want to make sure that users think it’s worth the price overall!

Homework h5.c - sp24.

DISCUSSION THREAD

homework link 7 5

NOTE: The view of the figure provided is that of the rod as seen from above the surface on which the rod lies.

Any questions?? Please ask/answer questions regarding this homework problem through the "Leave a Comment" link above.

20 thoughts on “Homework H5.C - Sp24”

Does a frictionless horizontal surface mean that it is on a horizontal plane?

Correct. This means that gravity does not need to be taken into account

Is there a normal force to account for in this question?

The only normal force would be opposing gravity, coming out of the page. Since this is in the horizontal plane we do not need to account for gravity and therefore we do not need to account for the normal force. The only force in your FBD should be force F

Would kinamatics be required for this question? If F is the only force acting on the rod I believe the question can be solved just through Newton/Eulers, would this be correct?

If in any kinetics problem in this course that you find that you do not need kinematics, then simply write: "Step 3: kinematics - NOT NEEDED.

In this problem, you do not need kinematics.

This is correct. You do not need kinematics in this problem since there isn't a problem where we have too many unknowns. The inertia is of the center of mass which is 1/12mL^2 based on the chart for inertia in our lecture book. Dividing F by g will give you your mass to solve a and b. Acceleration can be found by finding the force in the x and y directions and angular acceleration can be found by finding the torques that correspond to inertia times alpha.

MOI for a uniform rod around its center is 1/12 * m * L^2.

After solving for the acceleration of G, you will need to use M = IA (where I is moment of inertia and A is angular acceleration of the rod).

The mass is given in terms of pounds, which is mass*gravity. It's important to remember to divide this value by gravity in imperial units to find the mass alone when plugging into equations

Please note that the "weight" of the bar is given in terms of pounds.

I know that we need to use the M = IA Formula. However, I am confused on when we would use the (r cross ma) term if we are using the same equation and why it crosses out here.

For different problems, the 'r cross ma' term could be 'crossed out' for different reasons. Your goal should be to choose a point A such that this term goes to zero/ is 'crossed out'. In this problem specifically, if you choose the point A as the center of mass, then the position vector from A to G becomes a zero vector , and the whole cross product term goes to zero - simplifying our math.

I think it would be helpful to reference pg. 298 in the lecture book which explains it. This problem essentially falls into the first bullet point: by choosing the point of interest to be the center of mass, then the position vector is 0 and (r cross ma)=0. You would need to use the r cross ma when the point you choose is NOT 1) center of mass 2) fixed 3) with r(G/A) parallel to acceleration vector

All of the above cases have (r cross ma)=0, and we purposely choose a point such that we do not have to calculate r cross ma

When solving this hw, I did not need to use either accelerations to solve for each other. They were separate equations from the book. Similar to lecture

What helped solve this problem more easily is to remember that the Y component of the force being applied is cancels out when taking the moment around the center of mass.

The weight of the bar and the force acting on the bar are both given in lbs, so no unit conversion is necessary such as mg --> m

When dealing with a frictionless horizontal surface, we don't need to worry about gravity or its effect on the surface. We mainly focus on the force F acting on the rod, without considering motion equations. Remembering to use the moment of inertia formula M=IA is important, especially when figuring out how the rod rotates. Choosing A to be at the same location as the center of mass G, helps simplify calculations by eliminating unnecessary terms like r×ma. This method is all about making the math easier, as explained in the lectures.

In this problem, because the rod is in the horizontal plane and there is only one force, only kinetics are required to solve

You do not need kinematics in this problem since there isn't a problem where we have too many unknowns. The inertia is of the center of mass which is 1/12mL^2 based on the chart for inertia in our lecture book. Dividing F by g will give you your mass to solve a and b. Acceleration can be found by finding the force in the x and y directions and angular acceleration can be found by finding the torques that correspond to inertia times alpha.

Emergency call from ship allowed authorities to close bridge and save lives, Maryland governor says

From CNN's Andy Rose

An emergency call from the container ship gave officials time to begin closing the Francis Scott Key Bridge to vehicle traffic before the ship slammed into it, Maryland Gov. Wes Moore said on Tuesday.

“I'm thankful for the folks, once the warning came up and once notification came up that there was a mayday, who literally by being able to stop cars from coming over the bridge — these people are heroes. They saved lives last night,” Moore said.

No timeline yet for reopening Baltimore port to vessel traffic

From CNN's Chris Isidore and Hanna Ziady

Wes Moore, center, holds a news conference near the scene where a container ship collided with a support on the Francis Scott Key Bridge, on March 26.

The Port of Baltimore is closed to vessel traffic until further notice, and it's too early to say when ships will begin calling on the port once again, Maryland Gov. Wes Moore said Monday.

"Right now our exclusive focus is on saving lives, our exclusive focus is on search and rescue," he said at a news conference Monday.

The length of time that the channel is blocked by debris from the bridge will determine the extent of the economic impact of the accident on the local economy. While it could take years to rebuild the bridge — Moore described the process as "a long-term build" and one without a timeline as of yet. He added that removing the debris is likely to be a priority and could be accomplished much faster.

Some background: Overall, Baltimore ranks as the ninth biggest US port for international cargo. According to the Maryland state government, the port supports 15,330 direct jobs and 139,180 jobs in related services.

Until the channel is reopened, ships that had been destined for the Port of Baltimore are likely already changing course for other East Coast ports.

The DALI, the ship which hit the bridge and caused the collapse, was the only container vessel in the port at the time of the collision, but seven container vessels had been scheduled to arrive in Baltimore through Saturday, said Judah Levine, a researcher at logistics firm Freightos.

Bridge collapse may slow some auto imports and exports

From CNN's Peter Valdes-Dapena

A cargo ship is docked at the Port of Baltimore October 14, 2021, in Baltimore, Maryland.

A number of major automakers, including General Motors, Toyota and the Volkswagen Group, the maker of VW, Audi and Bentley cars and SUVs, use the Port of Baltimore to ship vehicles in and out of the east coast of the United States.

With Baltimore closed, automakers will now work to find other ports to bring vehicles in the US and to ship out ones that are manufactured here. GM, for instance, exports vehicles to South America and America through Baltimore.

"Our thoughts are with those who were affected and the Baltimore community," GM said in a statement shared with CNN. "We expect the situation to have minimal impact to our operations. We are working to re-route any vehicle shipments to other ports."

John Lawler, Ford's chief financial officer, said in a Bloomberg Television interview that Ford is rerouting auto parts to other East Coast ports. He said the situation will “lengthen the supply chain a bit.”

Truck traffic disruptions could cause issues even for automakers that aren't directly affected by port issues. Volkswagen's shipping facility in Baltimore, for instance, is on the eastern side of the bridge, and, so, continues to have access to the ocean.

"Last year, we received, processed and shipped approximately 100,000 vehicles through Baltimore for US dealers located in the Northeast and Mid-Atlantic U.S," VW said in a statement. "We do not anticipate any impact on vessel operations but there may be trucking delays as traffic will be rerouted in the area."

BMW and Nissan both said the bridge collapse would not greatly impact their operations.

Pete Buttigieg is heading to Baltimore today

From CNN's Kaitlan Collins

U.S. Secretary of Transportation Pete Buttigieg testifies at Capitol Hill on September 20, 2023 in Washington, DC.

US Transportation Secretary Pete Buttigieg is heading to Baltimore today, a staff member with the agency confirmed to CNN.

Buttigieg spoke to Maryland Gov. Wes Moore and Baltimore Mayor Brandon M. Scott following the collapse of the Francis Scott Key Bridge, according to a post from the secretary on X .

"Rescue efforts remain underway and drivers in the Baltimore area should follow local responder guidance on detours and response," Buttigieg wrote.

Maryland Transportation Secretary Paul Wiedefeld said in a news briefing Tuesday morning that authorities are searching for alternative transport options for the approximately 35,000 people using the bridge every day, noting that they will be directing people to use two major tunnels — the harbor tunnel and the Fort McHenry Tunnel — to avoid the site of collapse.

5 vehicles submerged in water have been found, Baltimore fire chief says

From CNN's Alisha Ebrahimji

Authorities have been able to find three passenger vehicles, a cement truck and a fifth vehicle submerged in the water using infrared and side-scan sonar technology , Baltimore City Fire Chief James Wallace told CNN.

Up to eight dive teams were in the water performing search and rescue operations, he said, noting he's unsure if the fifth car is a passenger or work vehicle.

"It's the dynamic of an incident like this, operating in a space of uncertainty, it just makes things very difficult," he said. "Add darkness to it, it becomes dangerous."

Singapore, where the vessel was registered, will launch investigation into ship that crashed into bridge

From CNN’s Sahar Akbarzai and Heather Chen

Singapore’s Maritime and Port Authority (MPA) announced it will launch an investigation into the container ship DALI and the bridge collapse in Baltimore, Maryland , according to a statement from the MPA on Tuesday.

The DALI is a Singapore-registered vessel, according to the port authority. 

The MPA said it is in contact with the US Coast Guard and will “provide full cooperation to the US Coast Guard in its investigations,” the statement says.

6 people are still unaccounted for after the bridge collapse, Maryland officials say. Here's what we know

From CNN Staff

A view of the Dali cargo vessel which crashed into the Francis Scott Key Bridge causing it to collapse in Baltimore, Maryland, on March 26.

The Francis Scott Key Bridge in Baltimore collapsed  early Tuesday morning after it was struck by a 984-foot cargo ship.

Here's what we know:

  • Six people remain missing: Maryland Transportation Secretary Paul Wiedefeld confirmed eight people were on the bridge at the time of the collapse. At least two people have already been rescued — one is in the hospital, the other is fine. The search continues for the other six.
  • Drones and sonar used in search operation: Authorities are carrying out a  search and rescue operation  using  sonar and infrared technologies  as well as drones, officials said. So far, they have identified vehicles submerged in the water. The  Baltimore branch of the FBI  is also at the scene, however the Baltimore police chief said there was no indication of terrorism as a motivating factor.
  • Ship lost power before crash: Video shows the moment the entire 1.6-mile-long, four-lane bridge crumbled into the water, after the vessel struck one of the bridge's pillars. CNN analysis shows that the  ships lights flickered  and it veered off course before it hit the bridge. Maryland Gov. Wes Moore said the crew on the ship were able to issue a "mayday" before colliding into the bridge, which allowed the authorities to stop incoming traffic from going onto the bridge.
  • More about the ship: The ship   was chartered by  Danish shipping company Maersk  and was carrying their customers' cargo, the Danish shipping company told CNN. The company said no Maersk crew or personnel were onboard the vessel. It said the ship, DALI, is operated by charter vessel company Synergy Group. 
  • Looking for transit alternatives: Wiedefeld said authorities are searching for alternative transport options for the roughly 35,000 people using the bridge every day, noting that they will be directing people to instead use two major tunnels — the harbor tunnel and the Fort McHenry Tunnel.

Insurers of DALI ship working to "establish the facts" following bridge incident

From CNN’s Caitlin Danaher

The insurers of the DALI container ship involved in a collision with the Francis Scott Key Bridge in Baltimore early Tuesday are “working closely with the ship manager and relevant authorities to establish the facts,” a statement from Britannia P&I Club said Tuesday. 

With head offices in London and Luxembourg, the Britannia P&I Club provides Protection and Indemnity insurance and Freight Demurrage and Defence insurance to shipowners and charterers, according to the company website.

Britannia P&I Club added it is working to “help ensure that this situation is dealt with quickly and professionally." 

“In the meantime, our thoughts are with everyone affected by this incident,” the statement added.

Ship issued "mayday" before colliding into bridge, governor says

Maryland Gov. Wes Moore said crew on the ship were able to issue a "mayday" before colliding into the Francis Scott Key Bridge, which allowed authorities to stop traffic from going on the bridge.

"We're thankful that between the 'mayday' and collapse that-that we had officials who were able to-to begin the stop the flow of traffic so more cars were not up on the bridge," Moore said.

New gmail security rules—you have 5 days to comply, google says.

New Gmail security rules to be enforced in seven days

Starting from April 1, Google will reject emails from bulk senders unless they meet new authentication requirements. This strict rule is aimed at reducing the amount of spam that lands in Gmail inboxes and enhancing the security of Gmail users. By implementing these new requirements, Google is aiming to prevent malicious actors from using unauthenticated or compromised domains to deliver their dangerous payloads and reduce unwanted spam.

03/27 updates below. This article was originally published on March 25.

New Bulk Sender Rules To Protect Gmail Users From Spam And More

Let’s face it: Gmail users get as much spam as anyone else, but most of it thankfully lands in the dedicated spam folder. That folder needs to be checked regularly for important emails that have been wrongly flagged as spam. But what if I were to tell you that, starting in just five days’ time, a whole bunch of spam will be blocked before it even has a chance to hit your inbox? Furthermore, the same new rules requiring proper domain authentication from bulk senders will increase email security for Gmail users. Here’s everything you need to know about Google’s new security rules for anyone sending email in large volumes to Gmail users.

Google’s Bulk Sender Definition

Google defines a bulk sender as anyone sending “close to 5,000 messages or more to personal Gmail accounts within a 24-hour period.” It should be noted that this includes all emails sent from the same primary domain, regardless of how many subdomains may be used. Meeting that bulk sender status once marks you as a bulk sender permanently as there is no expiration date to the categorization. As already noted, the bulk sender guidelines only apply to emails sent to personal Gmail accounts. However, all senders must abide by the new regulations and that includes those using Google Workspace accounts to send email.

Strict Domain Authentication Rules To Start April 1

In a Gmail product update notice posted October 2023, Gmail’s group product manager, Neil Kumaran, explains that “many bulk senders don’t appropriately secure and configure their systems, allowing attackers to easily hide in their midst.” Validation that someone sending email is who they claim to be, particularly when we are talking about those sending large volumes, is a critical requirement as far as email security is concerned.

That’s why, beginning April 1, all bulk senders will be required to authenticate their email using “well-established best practices.” Best practices like Domain-based Message Authentication, Reporting & Conformance, DomainKeys Identified Mail and Sender Policy Framework. “Ultimately, this will close loopholes exploited by attackers that threaten everyone who uses email,” Kumaran says.

This type of email authentication should be a given for any professional marketer seeing as how it diminishes the risk of spoofing or hijacking by malicious or unethical senders. You will have noted I said diminish and not eradicate as, unfortunately, there are still ways around such measures including SubdoMailing . However, a Google spokesperson told me that “Gmail has multiple layers of protections, and we’re constantly adding more to defend against this attack vector.”

Click To Unsubscribe Will Become Mandatory On June 1

Starting June 1, all bulk senders will have to include a one-click unsubscribe option. Anyone who has tried to unsubscribe from a mailing list will appreciate how convoluted a process it can be. Kudos to Google for trying to make this process not only easier for Gmail account holders but also quicker. The June 1 regulations will also require those bulk senders to process unsubscribe requests within 48 hours.

03/27 update: And talking of one-click unsubscribe options, a feature you would think that nobody could take issue with, a claim that Google is indulging in election interference by asking Gmail users to unsubscribe from emails sent by the Donald Trump campaign has gone semi-viral on X (formerly known as Twitter.)

The claim has been made by accounts from some of the most significant Trump-friendly accounts to the most petite, many of the latter looking very much like disinformation bot accounts with a handful of followers. The posts on X are not templated and appear to be posted in good faith by many of the posters. However, they typically claim election interference and suggest that Google is actively trying to steal the 2024 Presidential election by asking Gmail users to unsubscribe from Trump newsletters.

Those that include screenshots of the supposed political interference intervention from Google reveal that what is actually happening is Google is offering Gmail users the opportunity to unsubscribe from a mailing list where that user has not opened any emails to read them for a month or more.

There is even a community note added to some of the more prominent account postings on X, which provides the facts of the matter: “Google rolled out an ‘inbox tip’ feature in 2017 that identifies senders whose emails have not been interacted with over a long period of time. This feature is not unique to emails from President Trump or any other political mailing.”

The fact-checking site Snopes has also investigated the Trump unsubscribe claim and concluded that it is false: “…social media influencers misrepresented a feature Google introduced in 2017.”

ABC 10 News has also debunked the claim in its Fact or Fiction segment. The description of the segment video posted to YouTube goes one step further than most fact checkers, twisting the election interference claim around and suggesting “some conservative social media influencers are claiming Google is trying to interfere with the election by suggesting Gmail users unsubscribe from Donald Trump's emails.”

HOUSTON (AP) — Texas Attorney General Ken Paxton on Tuesday agreed to pay nearly $300,000 in restitution under a deal to end criminal securities fraud charges that have shadowed the Republican for nearly a decade.

The announcement by special prosecutors in a Houston courtroom came less than three weeks before Paxton was set to stand trial on felony charges that could have led to a prison sentence. It was the closest Paxton — who was indicted in 2015 — has ever come to trial over accusations that he duped investors in a tech startup near Dallas.

Under the 18-month agreement, the special prosecutors would drop three felony counts against Paxton as long as he pays full restitution to his victims, and completes 100 hours of community service and 15 hours of legal ethics education. A former special prosecutor said the chance of a conviction was going to be “50-50.”

Paxton said little during the hearing, and he avoided reporters by leaving the court through a back door.

But in a statement released later Tuesday, Paxton — one of the nation’s most prominent state attorney generals, who just six months earlier was acquitted of corruption charges in an impeachment trial in the Texas Senate — remained defiant.

Prosecutors announced an agreement with Paxton that would ultimately dismiss securities fraud charges he has been facing for nearly a decade. (Yi-Chin Lee/Houston Chronicle via AP)

“There will never be a conviction in this case nor am I guilty,” said Paxton, while thanking his family and supporters “for sticking by my side.” The agreement lets Paxton remain in his elected position and doesn’t affect his law license.

Dan Cogdell, a Paxton’s attorney, said prosecutors would never have been able to prove their case at trial, but he conceded that it was cheaper for Paxton to accept the agreement.

“Number one, the economics are actually in his favor for not going to trial. And number two, it’s a guaranteed dismissal at the end of the day,” Cogdell told reporters.

Houston attorney Brian Wice, who was one of the special prosecutors, described the deal as a victory that requires Paxton to repay investors, including Byron Cook, a former GOP lawmaker who served with Paxton in the Texas Legislature, and the estate of Joel Hochberg, a South Florida businessman who died last year.

Wice, who previously indicated that he would consider a pre-trial deal a “slap on the wrist,” said he and fellow prosecutor Jed Silverman reevaluated their chance of success based on evidence and witnesses.

“Our primary duty is to do justice, not to convict. So, the question isn’t whether or not who won, but was justice served? And I think the answer to that is unmistakably yes,” Wice said.

Kent Schaffer, who worked as a special prosecutor on the case until February and had tried to broker a similar settlement, said insufficient resources and antagonistic witnesses could have hindered the prosecutors’ case.

“I didn’t think we had a bad case, but it’s 50-50. It could go either way,” said Schaffer, a Houston-based criminal defense attorney.

The Cook and Hochberg families said in a statement they are “grateful that they will receive restitution in full.”

Wice acknowledged the long arc of the case that shuffled between four different judges over the years, ping-ponged between courtrooms in Dallas and Houston, and was slowed by the aftermath of Hurricane Harvey in 2017.

The resolution of the securities fraud case furthers a dramatic reversal of political fortune for Paxton, who just a year ago appeared imperiled by the criminal case and the threat of being removed from office after his top aides reported him to the FBI.

But Paxton has emerged emboldened. He waged war against dozens of GOP lawmakers who were part of the 2023 effort to impeach him, with his biggest target being state House Speaker Dade Phelan, who was forced into a May 28 runoff. He has also not ruled out a primary challenge to Republican Sen. John Cornyn in 2026.

Paxton still faces legal troubles, however. A federal investigation has been probing some of the same charges presented in his impeachment and former aides who reported Paxton to the FBI are trying to make him testify in a whistleblower civil lawsuit.

The securities fraud case has hung over Paxton nearly his entire time in statewide office. Yet the 61-year-old has shown political resilience time and again, winning over conservative activists, and importantly within the GOP, former President Donald Trump.

Paxton had been accused of defrauding investors in a Dallas-area tech company called Servergy by not disclosing that he was being paid by the company to recruit them. He was charged with two counts of securities fraud and one count of not being registered as an investment adviser.

James Spindler, a professor of business and law at the University of Texas at Austin, said it was surprising that Paxton even faced a felony prosecution. He described one of the charges — failing to register as an investment adviser — as a technical violation and said most similar cases are settled as civil lawsuits.

Legal experts have said over the years that the longer the case drags on, the harder it would be for both sides.

Paxton was also charged in a federal civil complaint filed by the U.S. Securities and Exchange Commission over his work with Servergy. But a federal judge in March 2017 dismissed the complaint against Paxton. The person who recruited Paxton to work with Servergy, ex-company CEO William Mapp, was found liable by a jury for misleading investors and ordered to pay a civil penalty of $22,500. Mapp lost his job with Servergy and later had to work as an Uber driver to make ends meet, according to court documents.

The fraud allegations were among the original 20 articles of impeachment but were set aside during the impeachment trial in the Texas Senate last year.

Paxton’s political opponents, most notably Republicans, had used the fraud charges against him in elections. But Paxton has twice been reelected as attorney general since his indictment, most recently in 2022.

This story corrects the spelling of the name of one of Paxton’s attorneys. He is Dan Cogdell, not Don.

10 things to know about the Phillies for the 2024 season

Bryce Harper joins a long list, Rhys Hoskins returns, and more fun facts to know going into season No. 142 for the Phillies.

Bryce Harper will play his first opening day as a first baseman on Thursday.

Some facts, some fun and even an agonizing anecdote at the end as the Phillies start season No. 142 in their history on Thursday against the Braves.

First base trivia : Bryce Harper will be the 10th opening-day first baseman for the Phillies since 2000. The previous nine are Rico Brogna (2000), Travis Lee (2001-02), Jim Thome (2003-05), Ryan Howard (2006-11; 2013-16), Ty Wigginton (2012), Tommy Joseph (2017), Carlos Santana (2018), Rhys Hoskins (2019-22), and Darick Hall (2023).

Hoskins and the Brewers visit Citizens Bank Park June 3-5.

London calling : The Phillies play the Mets at London Stadium on June 8-9. The Fightins’ will be designated the road team on June 8 and the home team on June 9. This is MLB’s third series at London Stadium, which was built as the facility for the opening and closing ceremonies for the 2012 Olympics. Offense has been plentiful in the previous four games held in London between the Yankees-Red Sox (2019) and Cubs-Cardinals (2023). The run totals for the four games were 30, 20, 10 and 12. The combined batting average in the four games was a healthy .339.

Kyle Schwarber could become just the second Phillies player to hit at least 40 homers in three consecutive seasons. Howard (2006-09) is the only one to do it.

When Harper signed with the Phillies in 2019, his 13-year, $330 million contract was the largest in baseball history. Five years later, Shohei Ohtani ’s $700 million deal is the largest, and Harper’s $27.5 million salary this year is 23rd among all major leaguers .

Ohtani — assuming the scandal involving his interpreter doesn’t go totally off the rails — will make his first visit to Philadelphia as a Los Angeles Dodger from July 9-11. Ohtani went 7-for-23 (.304) in his career at CBP when he was with the Angels, though he’s still looking for his first homer here. He’s never pitched in Philadelphia and won’t be pitching at all this season after elbow surgery.

That series wraps up a rugged nine-game stretch that starts with trips to Chicago to play the Cubs (July 2-4) and Atlanta (July 5-7). All three teams — the Cubs, Braves, and Dodgers — are favored to win their respective divisions. The final series against Atlanta is Aug. 29-Sept. 1 in Philadelphia.

Aaron Nola is 10 away from becoming the ninth pitcher to win 100 games for the Phillies. That list consists of Steve Carlton (241), Robin Roberts (234), Grover Alexander (190), Chris Short (132), Curt Simmons (115), Cole Hamels (114), Curt Schilling (101), and Al Orth (100). Nola (1,582) needs four strikeouts to pass Short for the third-most in team history. He’s not catching Carlton (3,031), but passing Roberts (1,871) and Hamels (1,844) is possible in a couple years for the 30-year-old Nola.

A quick look at some BetMGM Phillies’ odds as of Saturday: To win the division, 3-1 (actually +325); to win the National League 8-1; to win the World Series 15-1; to win 100 games, 5-1; to make the playoffs, 1-2; to lead the majors in home runs hit, 28-1; to finish last in the NL East, 40-1. Their over/under win total is 89.5.

New utilityman Whit Merrifield was 27 when he made his major-league debut in 2016 with Kansas City. His persistence has paid off to the tune of 1,184 career hits, three All-Star appearances, and more than $25 million in earnings. Merrifield’s father, Bill, hit 19 homers in triple A in 1987 and was called up by the Pirates. But — in a Moonlight Graham moment — a rainout ruined what would have been his debut, and he was sent back to the minors, never to reach the majors again.
