Hi folks,
I have a list of 10,000 people which exists outside of Dynamics 365 marketing database. It has a unique identifier included. How can I create a dynamic segment of these 10,000 people inside marketing module? To do this, I need a field which I could query inside a segment which can identify these 10k people. Do I first need to re-import these 10k people into D365 and put a specific unique value inside an existing field for these records and then query that field to check for that value? OR is there a better option to identify these people? Asking this since I though about putting a standard comment code for these 10k people but don't know if that will work. In the end I just need to send a marketing email to these people using a segment.
