How do I exclude email addresses from a send? In other words, I want to send an email to everyone on list 1 but also make sure no one on list 2 receives it.
List 2, an exclusion list, would work like the suppression list, but be a special case for one specific project.
You'd have to somehow create a segment that only included list 1 and send to that. Unfortunately there's no way to say "Send to everyone except this segment, you have to make an inclusive list of everyone else.
