What Hacker News says
5 sourcesJMAP sounded promising several years ago, and it was great to hear it published as a standard. But it seems like it’ll just remain as what Fastmail (the email provider) uses. Maybe the JMAP team is very small and can’t get more people. Maybe Fastmail doesn’t have enough money and/or enough interest to make it easier to use and to evangelize it with major email providers and email client developers.
I don’t see Outlook365 or Gmail (or even Apple for its iCloud email that has a relatively smaller user base) announcing any implementations of JMAP on their services. I don’t see smaller paid email service providers announce support for it. As it stands now, I don’t see a future for JMAP outside of Fastmail.
A popular client like Mozilla Thunderbird still hasn’t started implementing JMAP [1] and one of the reasons is because…the client and serv

As far as I know, at least one of the European countries requires it for some new projects.
In FairEmail: Open-source, privacy friendly email app for AndroidI haven’t been working on the JMAP stuff (I only started working there this year and I’ve been focusing on our new product Topicbox), so I’m not aware of all the details; but JMAP standardisation is going through the IETF, so you can see things that are happening with it at https://datatracker.ietf.org/wg/jmap/documents/ and https://github.com/jmapio/jmap/issues.
In Mailspring: A fork of Nylas Mail by one of the original authorsFastmail is great. They're also doing a lot of interesting work to bring mail access protocols out of the dark ages with JMAP.
