Our users get a lot of notifications from Jira. The ones that really matter are the comments in which they are mentioned. We want to create a notification scheme that just sends an email when a specific user is mentioned and removes all of the other notifications, particularly for system and project administrators.
I did not see an EVENT for a "mention" so I cannot add a notification just for that. I only see a "comment" event. Nor did I see a "role" of "mention.
As a project admin I completely ignore all jira notifications as I get too many of them and I routinely miss questions from my team that are directed to me.
Something that helped me is using a custom Stylesheet (with Stylus Chrome / Firefox extension) which can at least highlight mentions/comments in the notification feed.
It works directly in Jira as well as the Atlassian notification page:
I wish I had an answer to this. This is something that drives me crazy. The best workaround I've found is a combination of email filtering in outlook and setting up a JQL filter that I manually check once a day or so (if you add "comments ~ currentUser()" to a JQL query, it pulls up issues that mention you).
