Problem
You are receiving unwanted emails from a specific sender and want to stop them from appearing in your inbox. Alternatively, you may have blocked someone previously and now need to reverse that action.
Blocking senders in Yahoo Mail prevents messages from reaching your inbox, helping reduce spam and unwanted communication.

Use Yahoo Mail’s built in security settings to block specific email addresses. You can also review and remove blocked addresses at any time.
Step-by-step instructions

Go to:
Log in to your account.
Block an email address from a message
Open the email from the sender you wish to block.
Click the More icon in the email toolbar.

Go to:
Open Settings and select More Settings.

In the Blocked addresses section, find the email address.
