is it possible to check if a user would get multiple emails by beeing member of multiple groups which get email notifications?
A notification to GroupA would notify User1 and User2. A notification to GroupB would notify User2 and User3.
If I send a notification to GroupA and GroupB User1 and User3 would get notified once and User2 twice. The question is how to send only one email to User2 if he is in multiple groups getting notifications.
