You can set up “rules” in AWeber to automatically segment your audience, but these rules simply subscribe or unsubscribe people from various lists. For example, when one person joins list B, they can be automatically unsubscribed from list A. This simple rule is particularly useful when you have a non-customer email list, and a customer email list.
After you have entered your "List Name" you will need to enter a "List Description." Here is where you will describe the kind of information you'll be sending from this list. There is a 400 character limit for the "List Description." Subscribers will see your "List Description" on the unsubscribe page if they ever go to unsubscribe from your list. Once you are done entering your "List Description" click the "Next Step" button.
