Year 2000. Ended in a support role (think SRE 20 years ago).
Whe had a shared email account for the whole support group.
We received about 100-150 emails daily from people and automates processes...
... And nobody was allowed to archive or move mails to folders.
Almost 20 years later I simply don't trust email for important stuff. If I have to email something important I want to talk with the person, too.
When they wrestled that mail-server from under my desk in my apartment.
(No they didn't; it's an imaginary future doomsday scenario).
When I stopped using a combined inbox for life and work.
When subscribed on different mailing lists...
I didn't.
Or rather I took back control. I have now 2 email addresses - one for humans, one for the rest.
And I systematically unsubscribe from every email I don't want to receive (gosh I miss Europe for that), I delete everything that I have no reason to keep, and I archive anything that needs to be kept.
It demands a lot of effort at the beginning. But now my inbox is useful again.
