I used the Data Designer to link Contacts to some other information in a few Data Extensions. The links were done by primary key (1:1), either Subscriber Key or Email Address (both unique to contact). This created an Attribute Group.
Let's say it's something like the below:
Contact -> (Email Address) -> FlagA -> (Subscriber Key) -> FlagB
where FlagA and FlagB are Data Extensions with
(Email Address, FlagA) and
(Subscriber Key, FlagB).
Now, I want to filter
Email Address, FlagA = a, FlagB = b into a data extension so I can send an email to this segment of my users. I'm having a hard time creating a data extension off an Attribute Group.
How do I send an email to this filtered attribute group? I may be severely misunderstanding linked Data Extensions, but this should be doable as per the documentation:
For example, you can use the email address from a contact record to link to another data extension that contains product and shipping information. The contact record can then draw on any information uploaded to the product and shipping information data extension without changing the information in the contact record. That link allows you to create filters based on whether that email address links to a specific product order.
