Data lists can contain any data. Usually this is additional information about the contact such as preferences, loyalty card info, order info, contest and survey answers, etc.
They are 1-on-1 or 1-on-many linked to the Audience list.
- With a 1-on-1 (1:1) linked list, the contact only has one record in the linked list.
- With a 1-on-many (1:N) linked list, the contact can have many records in the linked list.
Only the ID of the record is predefined. All the other fields are custom.
