Epistles Mail

Epistles is a fast, powerful email app for people who use more than one provider. Bring Fastmail, Gmail, Microsoft 365 / Outlook, ProtonMail, and generic IMAP accounts into one unified inbox, with the polish of a premium client and architecture built for real-world email.

MULTIPLE ACCOUNTS, ONE EXPERIENCE See everything in one timeline or drill into a single account when you need focus. Switch providers without switching apps.

NATIVE WHERE IT MATTERS Built as a real native mobile experience. Responsive gestures, solid offline behavior, and attention to the small details that make daily email less painful.

PRIVACY-FIRST DESIGN Epistles is not an “AI that reads your threads” product. Your mail stays oriented around you and your providers, not server-side content mining for ads or training.

ZERO-KNOWLEDGE CLOUD VAULT Cross-device setup backs up connection metadata with encryption designed so the relay can’t unwrap your secrets.

LOCAL-FIRST SYNC Keep working when connectivity is spotty; sync when you’re back online.

WHO IT’S FOR • Multi-account professionals juggling work and personal mail
• Power users coming from Fastmail, Gmail, Outlook, or Proton who want one inbox
• Anyone who wants a universal client without giving up control

Epistles is independently developed with a simple goal: make excellent email software that respects how people actually use email today. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
