Hello, and welcome to the Adobe Marketing Cloud community.
Subscription and membership with Creative Cloud is not quite the same as with Adobe Marketing Cloud - with the latter, you (or your organization) subscribe to one or more of our digital marketing solutions. I recommend that you take a look here to learn more about what exactly Adobe Marketing Cloud is:
