Ah thanks. Sounds like you had it quite easy to be honest, and you must not get a lot of emails at all. Not every email is an action item for me—many are just for record-keeping purposes and later searchability, though I have certain filters for those to mark the occasional ones that require action. I would go absolutely insane if I had to look for even 0.1 seconds at every email.
My email style is inbox everything and route emails to folders or delete on read.
If there’s something I’m always routing without reading then I unsubscribe.
Workflow may not be for everyone, but it keeps my email under control and organized.
