(Shame on me for not finding out about this earlier, but maybe there are more people like me 😉 )
As a frequent SAP Jam user I’m somewhat used to receiving a bunch of emails per day for new posts in my groups or direct messages. I never really cared a lot about the emails, I would usually just open Jam occasionally and look at stuff there.
What _did_ bother me was the onslaught of “xxx mentioned everyone” emails which were mostly from groups trying to get my attention. That worked, but not in a good way.
Today I finally started complaining (nicely) in one of these groups, and Christian Happel replied with the solution in email (to avoid another @@notify email), which I’m happy to share here.
Meanwhile Christian has written a blog with the details – hope you’ll find it useful.
(it seems not everybody can access that blog, so I’ll copy&paste the essentials here)
If you go to your Account settings and navigate to the Email settings, you will be able to see all your groups on one screen and you can easily customize them all at once.
Or if you are receiving a lot of emails because people are using the @@notify feature in some groups: Here’s where you can opt out of email notifications for that.
