If you’re like most people, you probably use Yahoo Mail to keep in touch with friends and family. But if you want to stop using it, there’s a few steps you can take to do so. First, open the Yahoo Mail app on your phone and sign in. Then click on the three lines in the top left corner of the main screen and select “Delete account.” You’ll be asked for your password and other information. After you’ve entered all of this, click on the “Delete account” button. If you have any questions about how to delete your Yahoo Mail account, please contact customer service at 1-800-Yahoo (1-800-822-5227).
