1. Log in to cPanel.

2. Scroll down to the "Email" section and click the "Email Accounts" icon.
   

3. In the "Email Accounts" section, find the email account you want to delete and click the "Delete" button next to it.
   

4. Confirm that you want to delete the email account by clicking the "Delete" button in the confirmation window.
   

5. The email account has now been deleted and its associated email messages, contacts, and other data will also be permanently removed.
