In some settings, the contact email is Cced on “thank you” messages that are sent to users changing trust levels, and other similar emails. Can those be muted?
I’m not certain how this came to be, but it’s quite a lot of messages and their usefulness is not always obvious to the contact team.
So if you configure a user in site contact group name then that user will receive a copy of all those PM’s.
If you don’t want to get notifications for those, you should change the email notification settings for that user.
But then a user is not a group, so only one person will receive those messages.
I think the issue here is not about who received notifications or not, not whether they are sent on the site or by email.
The issue is information overload. There should be a way to allow a group of people to receive contact email, while not being notified of every single change of trust levels. The latter initiation is important, but surely there are other ways to track it. Contact emails should be reserved to humans trying to contact humans.
