I have considered hosting an instance but my ISP has vague terms prohibiting that sort of thing.

Have you had any issues with your ISP?

As far as I know email is an entirely different protocol than the fediverse so they wouldn’t coincide. It’s possible someone hosts an email server alongside their fediverse server but that’s not really the same thing as it being part of the fediverse.

I have a server setup with TrueNAS Scale installed and I would love something as simple as a Lemmy app for TrueCharts. I know TrueNAS scale uses k8s for apps so this should be possible but from my limited research it seems like something I’d have to figure out on my own for the most part.
