You can host them at apple if you have iCloud+, the cheapest of which is 0.99. MS charges you about half of Gmail (through resellers) if you don't want the office programs installed and about the same if you want that included. Zoho mail is about 3 dollars a month and then there is that service I can't remember (just email?) that will let you host the entire domain for 10 a year. Neither of which is very expensive.
