Does Fastmail really get push? I have a vague recollection that the reason I’m using their app over native ios Mail is because ios Mail was notifying me about emails with a noticeable delay.

It is “notify to pull”.

IMAP servers through APNS ping the iOS Mail about updates in certain pre-registered inboxes. Then iOS Mail re-fetches those inboxes.

The change signal is pushed; the data (inboxes/emails) aren’t.
