Ask HN: Where do you responsibly host your personal/small-biz email?

After a number of years with Google Apps for Your Domain (which you can't sign up for free for anymore, anyway), I'm beginning to both worry that AfyD's free service tier won't last, and that Google doesn't necessarily have my best interests in mind (in part because I'm not paying them).

Previously, fastmail has crossed my radar as a potential host that would have the proper balance of technical competence and valuing user privacy/security, but that's really all that comes to mind. I'd prefer not to self-host; keeping my main contact avenue functional should be a decision, not a project.

Any suggestions?

Thanks in advance!
