I was ruined for bug trackers by RT (https://bestpractical.com ). Driving issue tracking from email is brilliant - I only had to look at the application for reference or planning, all the normal back and forth happens from email. (Optionally - you can of course type in a web browser if you prefer.)
Jira's email behavior is pointless to the point of being counterproductive, and I disabled it. I have to look at it constantly anyway, why would I want it peeing in my inbox, too?
Of course, those who hate email are would react to it differently.
