Hi @Frankie_P, This does not seem like a practical solution in my case. I had a list of several thousand people who were receiving Email A, and a list of a few hundred people (who were also on the list for Email A) who were supposed to receive Email B, and not A. Since there is not an Exclude feature, I would have had to create a new List that included everyone for Email A *except* the people who were on the list for Email B. Since I am not an Excel master, I was not able to find an efficient way to do this, so I just had to accept that some people would receive an unwanted second email. With an Exclude feature, this would have been very easy.
