I'm using Hey, and while there are some issues with the company (namely, the CEO enacting some shitty employee policies during the pandemic), their email service is great.

Particularly, I love their email allowlist. Whenever you get an email from a new sender for the first time, you have the option to allow or deny their emails from then on. I used to always have thousands of unread emails when I was on Gmail (most things just routing to an unused "Newsletter" folder), but now, pretty much every email I get is one that I actually want to read.

It's a paid service, and tbh debatable whether or not it's worth the price, but the screening feature singlehandedly makes it worthwhile for me.
