All lists are initially assigned a default list name, which we recommend that you change to something more relevant to your business or campaign.
While subscribers won't see this list name in your messages, you will see it in your account, and should change it so that as you create new campaigns, you can easily tell them apart in your account.
Step By Step Instructions
Locate the List Options menu in the navigation bar and click List Settings. The first textbox on this page contains your current list name. Change the name in the box.
Your list name can be up to 32 characters long and should reflect the campaign so you know specifically what the list is about.
