Unless you're crazy like me and host your own email server :)

I like the direction Lemmy and Kbin has provided in terms of providing a messaging environment on the internet where it is more decentralized much like the internet of old.

Email on the other hand has taken a serious step in the other direction with email monopolies from the big names such as Google and Microsoft etc that have made self-operated email servers quite a bit more difficult to operate then it really should be, at-least from the perspective of actually sending email to other people using their servers and getting it in their inbox.

I find it ironic that Google/Microsoft etc use the excuse of spam/malware as the excuse to block self-hosted email servers with little to no email history/reputation yet most of the worlds spam comes from their servers.
