Wow. Impressive research.
Care to throw in a couple of free inbox providers for custom domains very low volume (20-50 mail/ mo)?
I already have Mxroute.
Edit: Looks like I can hack together something with Mailgun
Free ??? Yandex for domains. Mail.ru also offers it, but no experience with them.
Recommended providers: BuyVM - MXroute - LunaNode - Forpsi - IntoVPS

Kind sir, a little birdie (or was it a pigeon?) told me that you should mention Zoho Campaigns here.
Since the peer group is mailchimp, constant contact, etc. This is independent of zoho mail.
Inbox dot eu used to be a good option but (good for them!) not it is a palid plan

Zoho is perfect for any small business or startups.
I have been using them for my mail server, internal wiki, remote support and so many other things.

https://tinyletter.com/site/about/ is a newsletter service that is now part of mailchimp. I think it wasn't before, so I guess it was acquired at some point. I've never used it from the sending side but there's a newsletter I receive through it, and it's nice, less full of annoying tracking links and other crap than typical mailchimp-style newsletters.
