I also got lots of JIRA, Jenkins, Travis, Cron job notifications, until I filtered all of them away, straight to trash.
If I'm reading emails it means I'm not working or enjoying myself. And I'm not dev-ops, which means I'm not getting payed to keep the systems up and running at night.
I'm also practicing my own extreme version of "inbox zero". Whenever my Inbox reaches 100 emails, I select them all, mark as read, then archive. Information loses value as time passes and I figure that if there was anything important in there that hasn't caught my attention and that I did not answer, then one of my colleagues will surely buzz me about it. Worked fine thus far. And because I'm regularly removing noise, it means I have a higher chance of actually noticing important messages.
Writing this message reminded me that I've got 40+ unread emails in my Inbox. Marked as read, archived, now it's a solved problem.
