In order to create, edit and delete email accounts, you need to start by logging into your hosting account's cPanel.
You can access this by going to: https://yourdomain.com/cpanel
The login information for your cPanel would have been emailed to you when your account was set up. If you need this information resent, please ask our support team.
Once you are logged into your cPanel, look for the icon that says 'email accounts' and click on it. This will bring you to the email accounts area of cPanel.
In the email accounts screen, you can add a new email account at the top of the screen, and just below that is a list of the current email accounts. Beside each current email account are options to change the password for the email account, or delete it entirely.
For additional information, you can always click on the 'help' button at the top right of cPanel while you are logged in.
