Epistles Mail is an email app with a unified inbox, offline access, scheduled sending, and calendar tools. It works with Gmail, Microsoft 365, Fastmail, JMAP servers, iCloud, Proton, and IMAP. Mail content, attachments, drafts, and the search index stay on the device, and search runs against a local cache. Its local-first, zero-knowledge encryption model stores ciphertext in Cloud Vault; Epistles servers do not store mailbox content. The app is available on Android, iOS, macOS, Windows, Linux, and the web, as well as Apple Watch and Wear OS. The free plan supports up to two connected accounts. Pro costs $35 per year after a 14-day free trial and allows unlimited connected accounts, with password-protected, expiring email included. Pro uses one flat price rather than per-seat billing. iCloud support includes mail, calendar, and contacts. The watch app supports archive, snooze, pin, template replies, and RSVP. Epistles passed a CASA Tier 2 security assessment by TAC Security.
