We want our subscribers to be able to choose what lists they can sign up for, depending on interest. How do we add that choice to the signup landing page? How can they change what area they subscribe to = change list?
Make sure the Update Profile form is enabled in your account, and draw contacts' attention to its placement in your footer. The lists you select for the UP form will also show when a contact attempts to unsubscribe, in case they only wanted to unsubscribe from particular emails.
