To create an email account in cPanel, log into cPanel and click "Email Accounts". Enter a username using your domain name, set a password by entering it twice, and select a mailbox quota. Click "Create Account" and the new email will appear in the "Email Accounts" section. Access the email by clicking "More" and then "Access Webmail", where you can select a webmail application like Roundcube and view the empty inbox for the newly created account.
