You can use the same domain for your new account, but we will need to delete your old account so you can resign up again. We recommend not using your cPanel email address as your hosting account. Only use your personal email address. So that if you ever forget your password, that’s where it goes and get it from. For security reasons about getting your backup files, we only send everyone’s backup files to their email address that we on file in our system. So unfortunately, you will have to start all over again!
