Having WebPush style push notifications is a huge advantage of JMAP. Right now, 3rd party mobile email clients are stuck to polling every few minutes or keeping a connection open.

I'm looking forward to more JMAP adoption, especially on FOSS Android platforms.

The _Fastmail app_, which one might assume is the flagship client, doesn’t work at all offline. So I’m unimpressed. Every other non-Webmail client I’ve ever used, whether POP3, IMAP, Exchange, or proprietary, worked at least to a reasonable extent offline.
