Ask HN: What are you using to host your email?

I use the basic Google Workspace Business plan to host my email, but the price is increasing from $6/month to $7.20/month in a few days.

I also want to get away from Google services as much as possible.

Right now I'm considering using Amazon Workmail since I use AWS for a ton of things, though I guess that would put me in the AWS ecosystem.

What do you use?
