A superuser is someone who manages and maintains the Spotler MailPro account. This role has all rights and access. This also applies to the Setup and Admin modules, where many overarching account settings are managed. The superuser is often also the one who is in direct contact with Spotler. There can be multiple superusers within one account.
Am I a superuser?
Go to the Admin module > Users. Then search for your username in the list. Check whether the Roles column shows 'superuser'.
Don't see the Admin module? Then you are certainly not a superuser.
