tbh I'm with the zoomers on this one. Work email is 99% junk. Newsletters from every SaaS product we use, "A meeting started", invitations for calendar events that I can just accept ON the calendar, notifications for every transaction on every system ("X posted a comment on Y,") and spam from salespeople, recruiters, etc. And then 1% of it is actionable important stuff that I don't get through Slack.
