I'm currently building out an Engagement Program that consists of 2 separate streams for 2 different audiences (one called Group G and one called Group W). Group G and W receive the same content. However there CAN be situations when some one would be part of both Group G and Group W. I upload the lists that correspond to the campaign members as static lists, which are updated on a daily basis through manual upload.
How do I build out an engagement program that would ensure that one single individual would not run through both streams simultaneously? Or receive the same email twice? How could I capture who is part of both Group G and Group W?
