Does Yahoo earn money from your spam email box?
Yahoo earns money, in part, from displaying ads on each page, including each view of your e-mail. Additionally, they make more money if you click on one of the ads or follow a link. That is how they offer you e-mail without charging you for it.I suspect your real question is "Why do I get spam delivered to my Inbox in Yahoo that I don't see in other services?"
How does Yahoo spam detection work?
Nobody except Yahoo can answer this, and they won’t. Spam filtering at the scale that players like Google, Microsoft and Oath (Yahoo and AOL) handle costs millions and millions of dollars. Content scanning emails is computationally expensive and if any part of their process was compromised by spammers, it would cost them millions to fix it. This could be due to increased storage costs in accepting messages that should have been rejected at the gateway, more servers required to correctly filter spam (horizontal scaling), more CPU/RAM required to correctly filter spam (vertical scaling), better algorithms to filter spam (engineering/product development resources), etc.Spam filtering at any of the large companies is going to involve dozens or hundreds of variables. Here’s some examples:Is the IP address on an internal blacklist?Is the IP address on an external blacklist?What’s the IP reputation as measured by third parties such as Return Path or Talos?How many valid recipients have I seen from this IP address?How many invalid recipients have I seen from this IP address?What volume of mail do I get from this IP address?What historical behavior have I seen from this IP address?Have I seen the content in this message before?Did users respond positively or negatively to this content?Is the sender in the recipient’s address book?Has the recipient replied to emails from this sender before?Has the recipient opened emails from this sender before?Has the recipient flagged anything from this sender as important?How long did the recipient read this email?Did the recipient delete the email without reading it?…etc etc etc. It goes on forever. Any question you ask about IP reputation can also be applied to domain reputation, DKIM reputation, the ESP’s reputation, the ASN’s reputation, and so forth down the list. There are hundreds and hundreds of variables that go into accurate spam filtering at scale.Here’s a decent response from Yahoo on their spam filtering, but again, they’re not going to give detailed information (ever - to anyone) because any public information will only help spammers and cost their bottom line.Why did email go to spam?
Why is Yahoo so inept at blocking spam from my Yahoo email account? I get the same “Lonely Married Women” email every day. I understand that the spam email address changes every day, but why can’t Yahoo spam check the subject?
Actually, Yahoo! blocks a ton of spam. We have a team working very hard on this challenge that we all face. Check out this realtime view here: Visualizing Yahoo! Mail (make sure you click on the "reveal blocked spam" button) to see how much spam is being blocked at any moment. We block 4 messages for every 1 message we deliver.Still, you are seeing spam in your inbox which means that some comes though despite our attempts. But you can do things about this too.Remember to set the spam filter on your email client. If you are using the Yahoo! web client go to the Options tab and check to see that you have spam set to be filtered out and deleted.When spam comes though, please mark it as spam. We pick up that signal and it helps improve our algorithms. This way we can block more spam in the future for you and others.General tip -- make sure not to post your email address in full on a web site. I saw a report once that showed how spambots harvest email addresses from blogs and site by searching for "yourname@host.com" pattern but they don't search for "yourname 'at' host.com" So you can reduce your risk of inviting spam by making this small change.If you get a spam mail, don't click on the links. This sends the signal that you are a real person who clicks on spam. Just delete these emails. I'm sure you don't need the pills anyways.Did you know that Yahoo! also give you disposable email addresses that you could use, say if you are doing online shopping? This is another way to make sure that your email address is only used by your real friends, and that websites only see addresses you don't care as much about.Maybe these tips will help your emailing experiences. You've been with Yahoo! for 10 years, we hope you enjoy our services for at least 10 more too!
Why is Gmail so much better at filtering spam email than Yahoo! Mail?
Search technology or at the least the field of mathematics and computer science behind it, is readily re-purposed towards defeating the problem of Spam.See if you can follow the following sentence transformation, from problem to solution..."How SPAMMY is this NEW EMAIL?""How SPAMMY is this TEXT?""Can we compare SPAMMY emails to this TEXT?""Can we compare known SPAMMY emails to this TEXT?""Can we search known SPAMMY emails using this TEXT?""Can we search known SPAMMY and UNSPAMMY emails using this TEXT? "Can we search known emails using this TEXT?""Can we search known emails using this query?""Use this query to search known emails."If the results are spam, the query (email in question) is most likely spam.Of course this would have been the primary idea, but Gmail would use a bunch of other techniques as well - not least the sender address.Google, viewed as a vendor of web based email, had the advantage of having the world's best search scientists, an ocean of search related patents and massive search infrastructure.
Why is Yahoo mail's spam detection not as effective as Gmail's spam detection?
Yahoo spam detected was quite ok in the past (though I have never used Yahoo mail much), they have even implemented and published some well-known anti-spam methods like DKIM. It seems that in the recent past Yahoo didn’t do any development in that area anymore, probably because the company went down the drain and was now sold to Verizon (as was AOL). Gmail is continually developed further, so the spam filter is probably much more up to date (for example Gmail supposedly uses NLP and AI to analyze spams now to further improve spam detection)
How to stop yahoo groups invitation spam?
Unfortunately, I am having the same problem. I don't know if it does any good, but I have been sending each unwanted invitation to abuse@yahoo.com and abuse@yahoogroups.com. Maybe eventually they will add a setting letting us choose whether we are invited to a group or not.
Why does Yahoo perform such a terrible job at filtering spam?
This is a leading question, but I'll entertain it anyways.Perhaps the price Yahoo charges for ads that get displayed when you open marketing-content emails is higher than the price Yahoo can charge for ads that get displayed when they're from your grandma. That would suggest that email providers have an incentive to let "some" amount of spam in, because it makes them more money than your grandma emails do.Just a guess. But I assure Yahoo cares a lot about spam, and suffers from the "biggest target" problem, much as Microsoft became known for having viruses while Apple avoided that perception because they were simply not the most lucrative target. Yahoo is a very large target.
