Blocking Unwanted Senders Is Not Blocking Junk Emails

Don't let a large number of blockable addresses lure you into thinking you can fight spam with this method. Spammers can and often do use a fresh address (or domain name) for every junk email they send.

Use the list of blocked senders for individuals whose messages you do not want to receive. Instead of having to delete every new mail from each of these addresses manually, Yahoo Mail can do the cleaning for you.

Can You Block Senders From Yahoo Mail Mobile or the Yahoo Mail Apps?

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