Interesting that they call out Fastmail as a supported provider, but don't support JMAP. Seems like that would have been an easy stretch goal for Claude, and a good way to stand out amongst the competition.
I wouldn't say it's something that can be vibecoded in a month or two. Proper design and implementation take time if you want to handle accounts with hundreds of thousands of messages seamlessly.
These days with the convenience of having LLMs at developer’s disposal, it feels unjustified to use electron like apps.. whenever I see “one app all/multi-platform”, I feel discouraged to give it a genuine try.
I tried a bunch of email clients and then crawled back to mail.app + Calendar.app on MacOS simply for how native it feels.
Interesting. TIL about this. I added myself to the waitlist.
