But I disagree with
> all come with a modest price tag
The price tag may be modest for some people, but is not for everyone. If someone needs one mailbox per person in a family, the costs go up a lot with Fastmail. There are cheaper alternatives that have been around for long (though probably not doing things like developing new protocols such as JMAP). Some of these alternatives may also be suitable for people who don't want email to be hosted in the US.
I've got both, because I can buy 12+3 month O365 keys on black friday sales and stack them. I think my next bill is coming in 2027. Until then everyone in my family has a 1TB Onedrive account and full Office suite with email.
