I leave them enabled but email only, then I set up filters for each service to move it to */automated/jira directories automatically.

That way my inbox stays clear but I can speed run through first thing to make sure I’ve not missed anything, I also ruthless cull anything unrelated to my work, so any notification a project I don’t work on gets deleted.

This reduces several thousand emails a month to about 6 I actually need to see in my inbox.

The default is insanity though I agree.
