Block Email from Unwanted Senders in Yahoo Mail

Yahoo Mail lets you block emails from unwanted senders. When you block someone, emails they send you never make it to your inbox.

Yahoo Mail does not notify senders that you have blocked them.

  1. Go to Yahoo Mail in a web browser, log in to your account, and select the Settings gear icon in the upper-right corner of the window.

Blocking Unwanted Senders Is Not Blocking Junk Emails

Blocking email addresses isn't an effective strategy to prevent spam since spammers often use a new address (or domain name) for every junk email they send. Yahoo Mail has a built-in spam blocker that you can customize.

Can You Block Senders From the Yahoo Mail App?

You can only block unwanted email addresses in the web versions of Yahoo Mail. Try opening the desktop version in your phone's browser, or use a computer instead.

To monitor messages from specific email addresses rather than blocking them, set up a filter in your Yahoo Mail account to automatically send messages from a particular sender to another folder.
