I have two products (PRODUCT A and B). Some own PRODUCT A, and some own PRODUCT A and B. I want to only email PRODUCT A owners, but its impossible not to include the ones that own both in the email. Basically, there is an option to email "Active Users of", but is there an option to "but Do Not Email Users of"??? Anyone have any ideas with AMEMBER, or a different way to go about this? Thanks..
