If you want to delete your AT&T email account, there are a few different ways to go about it. The first way is to go to the AT&T website and sign in. Then, on the main page, click on the “My Account” link in the top left corner. On the My Account page, click on the “Email & Phone” tab. On the Email & Phone page, under “Account Type,” select “Mail Plus Web Services.” Under “Account Info,” click on the blue “Delete My Account” button. If you want to delete your AT&T email account but don’t have a web browser handy, you can also call AT&T customer service and ask them to delete your account for you. They’ll need your account number and password (if you have them), and they’ll be able to do it over the phone pretty quickly. ..
