That sounds great, but the problem I see with the n-address approach is when you do actually want to search for a received email but you don't want to remember what inbox it went to. I can see workarounds - like feed them all to a gmail box and filter them into their own folders. Or load them all into a native email client as separate accounts.

I felt that way about using a password manager and generating random passwords (what if I want to log into something and don't want to remember which password I used) but eventually realized that password managers are literally designed to make this as painless as possible and I should relax more. Now I use KeepassXC, random passwords and life is good.

Are email managers a thing, like password managers? How do you solve this problem?
