I use both. I have a self hosted docker compose instance of mailcow, which alerts me when an update is available.

I also use protonmail as well.

Self hosting was a pain in the ass to get working, but I’ve had no issues with it once up. I tossed it behind a reverse proxy to keep it from directly touching the internet.

I wish phones would go back to being unique. I want a slider with a physical keyboard (like the HTC EVO Shift). My Pixel 6 Pros battery is showing wear already but there’s nothing on the market I feel is worth switching to.
