Getting emails from a specific sender that you'd rather not see? If you know how to block unwanted emails in Yahoo Mail, you can automatically delete incoming messages from up to 500 email addresses.

Instructions in this article apply to the web versions of Yahoo Mail. All steps should be the same regardless of your web browser.

How to Block Unwanted Emails in Yahoo Mail

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

Open Yahoo Mail in your web browser and select the gear icon in the top-right of the window.
Select More Settings from the menu that appears.
Select the Security and Privacy category on the left, then select + Add.
Type the unwanted email address in the Address field under Add an email address to block.
Select Save.

How to Block Emails From Specific Senders in Yahoo Mail Basic

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

Choose Options from the drop-down menu, then select Go.
Select Blocked Addresses under Advanced Options.
Enter the email address you want to be blocked beside Add an address.
Select the plus sign (+) to add the address to your blocked list.

Blocking Unwanted Senders Is Not Blocking Junk Emails

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

Can You Block Senders From the Yahoo Mail App?

Unfortunately, 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.
