Your problem
I have a series of books. The user can visit a landing page for each book and then sign up for my newsletter. On the landing page, there is an option for the user to enter which book they have purchased. By knowing this info, I can divide my contacts into segments and send out specific newsletters to particular segments of user.
I have created a “Standalone Form” in Mautic and put in a field for the user to enter the purchased book.
However, how do I set it up so the data in this field is tied to their contact profile?
Also, a user could sign up multiple times (for different books), so I would want new data in the purchased book field to append the existing data rather than replacing it.
