Unique Recipients

If I have a email performance report that consists of 6 different emails. Is there a way to determine how many unique people received all 6 emails?

Level 10

Yes. By building a Smart List:

Level 2

I tried that and it says “No people found”

Level 10

Well, then that might be the truth. Nobody received all these 6 emails. Do you have good reason to believe otherwise?
