Adding Unwanted Email Addresses to Junk Mail Filtering List

Overview

You can direct email addresses to your device's block or filtering list. Blocked senders are people and domains you don't want to receive email messages from. Messages received from any email address or domain listed in your blocked senders list are sent directly to your Junk Email folder.

Note: Instructions will vary across device type and email software. In addition, there are options that may be exclusive to only desktop versions compared to mobile devices. The email app on your mobile device may not have the option to block senders, so you will have to log in to your desktop email instead.
