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.
One of the best features of AWeber is the ability to create a series of emails that are automatically sent out to new subscribers. This allows you to create an eCourse or some sort of introductory guide for your latest subscribers. This is fantastic as you can market it as an incentive for people to subscribe (e.g. subscribe and get our free 7 day eCourse) and once setup, you can leave it to be sent out automatically.
