I'm not sure I'm in your target audience--I guess it depends on where you set your bar for "spam".
5 of my last 100 emails got red, and the rest I don't intend to read. The unread bunch falls into these categories:
- Notifications of activity in Jira or Confluence (I go to the apps directly, so I don't need email notifications)
- Mass communications from HR, marketing, the CEO or some other entity that is too-many-hops away from my team to ever have anything relevant to my job.
- Meeting invites to meetings I attended anyway due to a conversation I had prior
- Servers letting me know about errors that I already expected due to conversations I had prior
- People telling me that some server I don't care about is down or up (presumably to stop inbound complaints)
- IT related communications (ex: new wifi password) from our parent company that aren't related to our site
About a year back I abandoned e-mail and only check it if somebody mentions something. So far I haven't missed it. Same thing with news. For both of these things I find that my meatspace social network already contains what I need (we also use slack pretty heavily, so the real work related communications happen there).
Yeah, maybe I'm out of the loop on some things, but it's hard to get work done in the loop.
