Need help with learning plans notifications

I have been looking into this myself. What I have been able to identify to stop this is removing the courses from the course notifications. The issue that arises is this will now require you to add every new course to the course notifications to assure others are communicated to about it.

Sure there is and ​@emily.mccarthy is calling to an aspect of it.

I would want to say consider this approach:

An LMS definitely should not be wired to be as chatty as it can be - and everyone should be saved the right level of communication to take action with.

Start with these three ideas:

1. I would actually disable any global generic all course and all audience or even a broad branch level types of notifications first for course completions.
   1. I would say that you would want to use specific groups to drive only certain types of notifications (like for onboarding/annual training). 
2. Use digests more to help to eliminate the many notifications as well.

There are other posts that resonate similar ideas - but some good news - the notification system is bound to see an overhaul in a few and that overhaul should be out to you into the next few weeks depending on where you sit. So actually being able to responsibly curate those is going to be very doable - even for things that feel out of control.
