I have also had random contacts dropped from groups. I don't know it until they call to ask why they aren't receiving emails anymore. When I check, they have been dropped from all of our groups within Constant Contact. So they are still in the system, just not assigned to any groups. They are not unsubscribed. I then re-assign them to the appropriate groups. My question is why is this happening??? I haven't taken them out of groups. This is getting to be a big problem for us.
