When you cancel an AT&T service, the AT&T email address, also known as a Member ID, associated with that account isn't removed. You can continue to use that email address as an AT&T free email account without any charge. If you’d like to delete the email address, you must do that manually. For email accounts that have never been associated with a paid AT&T service, you can delete them at any time.
