How to Block Unwanted Emails From Senders in Yahoo! Mail

If you're seeing emails from specific senders that you'd rather not see, Yahoo! provides a way to block them easily and never see another message from those senders again. In fact, Yahoo! Mail can block all mail from as many as 500 email addresses. All mail from these senders will be deleted automatically before you even see it.

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

Instead, use the list of blocked senders for individual senders whose messages you do not want to receive but cannot stop easily. Instead of having to delete every new mail from each of these addresses by hand, Yahoo! Mail can do the cleaning for you.

To have Yahoo! Mail delete all mail from a particular address automatically:

1. Hover the mouse cursor over the settings gear icon or click that gear.
2. Select Settings from the menu that has appeared.
3. Go to the Blocked Addresses category.
4. Type the unwanted email address under Add an address.
5. Click Block.
6. Click Save.

To add an email address to the list of blocked senders in Yahoo! Mail Basic:

1. Make sure Options is selected in the top Yahoo! Mail Classic navigation bar drop-down menu next to your account's name.
2. Click Go.
3. Open the Blocked Addresses category (under Advanced Options).
4. Enter the email address you want to be blocked under Add an address.
5. Click +.

No, you can block unwanted email addresses only in the desktop version of Yahoo! Mail. Try opening the desktop (rather than the mobile) version on your phone.
