Lot of work to do there.
It makes me wonder though. How much of that is just pure noise. Like 329 emails of notifications from some to-do app that a team shares where every single time someone clicks a little like button it generates an email.
I’m sure some people get literally thousands of personal emails a day, but I think most people under severe email load get buried from not managing notification settings, not unsubscribing from stuff, and generally avoiding even looking in there let alone engaging with that inbox.
