We are happy to introduce an enhancement to our world-class segmentation feature, the option to bring together “Fields from another mailing list” which enables cross-list Segmentation filtering.
With cross-list segmentation criteria you can segment the contents of a mailing list from criteria spanning across multiple lists in your account. Since the email address is the primary key between all of those lists, you can segment the members of this list, with information that exist in another list in your account.
For example, let’s say you have mailing list CONTEST with a Date of birth custom field where you store the date of birth of subscribers in that list. You also have another mailing list, called MAIN SITE where you only store the Name of the subscriber. You can say I would like to send a “Happy Birthday” campaign to list MAIN SITE where the user’s date of birth is today. This criteria will match the recipients that exist in both lists, you will have theirName and include those where the Date of birth is today. Combine this feature with the existing expression language (nested ANDs and ORs) and you get a yet more powerful segmentation tool.
Read here more about this powerful tool you have in your hands.
