Custom List Elements

Adding your own list fields is easy. Just go to:

Lists tab -> List Tools -> Custom List Elements

1. The Name is used internally so just pick a short but descriptive name. 
2. The Friendly Name is what you see in User Interface in the drop-down menus like when you add personalization to the subject line of content of the mailing. 
3. The Personalization is the tag itself (we handle this for you)
4. The Alias is what you would use when connecting with an API request.
