Totally agree! I bet tons of businesses would want this but actually don’t realize that all the subscription types are exposed for anyone to signup for, so don’t realize the issue. I didn’t even realize the issue until I accidently discovered it. We have “internal” subscription types for various emails to internal employee groups and divisions. I didn’t realize anyone subscribed to one of our other public facing subscriptions could see and subscribe to these. I am a bit baffeled that being able to better manage this kind of thing is not standard.
