Sometimes you accidentally give out your personal email address to an unfortunately persistent contact, or you want to stop seeing emails from a frenemy. Marking their messages as spam isn't enough, since you don't want to depend on spam filters to keep them out of your inbox. In Yahoo Mail, you can block up to 500 addresses from sending you messages. Here's how to make sure you never get email from someone again.  

1. Sign in to your Yahoo Mail account.

  • Ben Avi Says:

    What you've shown is how to block an ADDRESS - not a PERSON. Addresses can be changed. How about how to block a NAME? Spammers have algorithms that change the address just subtly enough to keep 'em coming... whether you've blocked it or not.

    How do I stop sexually related e mails from coming into my sons spam , junk folders. When I've tried to unsubscribe it doesn't seem to work. Also, is he really subscribing or is that just a scam. That's very important to me, if he's subscribing and then telling me that he is not then I have an issue with lying. Can you please give me some insight so that I'm armed with facts. I'm not savvy regarding these issues. Thank you for any help in advance, Laura
