@Adam I was referring to the "Group" feature. For example:

john_doe@none.com  is a member of groups "Product A" and "Product B"

jane_doe@none.com is a member of group "Product A"

I want to sent a mailing to everyone in group "Procuct A" excluding contacts that are also part of "Product B" 

In other words only send to jane_doe to cross sell to Product B. john_doe already has Procuct B so I don't want to email him to try to cross sell.

Thanks,

Ken

Ok, I see what you mean. If john_doe@none.com was only a member of Group B, it'd be easy enough to not include that, but since he's in A he'd be included.  If you haven't yet I'd recommend posting this to our Vote on Features board, since it'd be a useful addition to Promote.

Thanks Adam, I have added to the Vote on Feature section.

Nice - thank you, Ken!
