Rock Mail

Features
Read full description

Rock Mail is a fast, private mail app for people who run their own mail or use a JMAP or IMAP provider. It talks directly to your mail server — there's no Rock Mail account, no cloud in between, no analytics and no ads. JMAP FIRST, IMAP TOO Sign in to a JMAP server for instant updates, or to any IMAP and SMTP account. CONVERSATIONS Messages are grouped into conversations, with fast search that works even offline. PRIVACY BUILT IN Remote images are held back until you allow them, for one message or always for a sender. Known tracking pixels are removed. Your always-load list is stored on your own server so all your devices share it. RULES ON YOUR SERVER Create rules that file, flag or forward mail. They run on your server (JMAP with Sieve), so mail is sorted even when your devices are off. WORKS OFFLINE Read, reply, file and delete without a connection. Changes go out when you're back online, with Undo Send. NOTIFICATION BRIEFS On devices with Apple Intelligence, new-mail notifications include a short summary written on your device. ON IPHONE, IPAD AND MAC One purchase covers both, with a native Mac app: multiple windows, toolbar, keyboard shortcuts, and the option to make Rock Mail your default mail app.
