I'm trying to make HEY work as well. Can we start a side discussion about it? I was initially impressed but now it feels like I have a part time job manually flagging things that should have been seen as spam right away

I switched to using my own domain for important emails some 10 years ago, after a friend got his Google Account taken over while on a month long hike without internet. When he got back his account had been banned because they used it for click fraud, no way to contact Google to get it reinstated, he lost access to his GMail, with it all email history since 2004, logins to accounts tied to it, etc.

I don't want ever to go through this nightmare.

People actually paid for HEY? I tried out the closed beta for a bit and once they started asking for $100/year I very quickly decided it wasn't worth that.

It doesn't help you with existing emails, but you don't have to worry about receiving new ones.
