My marketing users have an existing data extension that they want to continue using when creating emails. We are implementing a new integration that will provide 15 new data points. It's my feeling that these new data points should be in a new data extension. But the problem with email studio, is I think you can only choose one data extension when setting dynamic content rules. If I have data from multiple data extensions that I want to use in setting dynamic content rules, what are my options?
Should I append the new data points to the existing data extension? Is that even possible?
Is there some way to pick the attributes I want from each data extension to make them useable in dynamic content? Besides picking a single data extension, you can choose an Audience or Profile Attributes. Will either of those work?
