How to Block an Email Address on Yahoo Email

Block up to 500 email addresses or domains in Yahoo Mail to prevent spammers or other people from sending you unsolicited or unwanted emails. Emails from people that are on the Blocked Addresses list are deleted before reaching your account. The owners of the blocked email addresses or domains are not notified when you block them. You can, of course, remove specific email addresses or domains from the Blocked Addresses list at any time.
