Proton Mail’s mobile apps just got their biggest upgrade in nearly a decade. We rebuilt them from the ground up to be faster, smoother, and more reliable — even offline. And, for the first time, iOS and Android are fully in sync, with the same features and updates arriving side by side. It’s a major step forward for the world’s most widely used encrypted email service. In this newsletter, you’ll find the highlights from the new Proton Mail apps, plus other recent updates to Proton Calendar and Proton Mail.

Proton Mail, rebuilt for speed

The new, completely redesigned Proton Mail apps for iOS and Android deliver faster and more reliable performance, even if you have to go offline. Everything at your fingertips: A clean new design makes it easier to navigate, with key actions like composing within easier reach. Performance that keeps up: Routine actions, like scrolling your inbox, archiving threads, or replying on the go, all feel instant and are now twice as fast. Offline mode: Read, write, and organize your emails without an internet connection. Sync happens automatically when you’re back online. Behind the scenes, our Android and iOS apps now share roughly 80% of their code, which means faster development and updates that land within the same release window across both platforms.

Secure your account with 2FA security keys

You keep important moments of your life in your Proton Account. Whether it’s bank statements you receive in Proton Mail or events you set up in Proton Calendar, your data deserves to be protected. You can now secure your account with hardware security keys for two-factor authentication (2FA) across the Proton Mail and Calendar apps on all platforms. This ensures only you can access your account using a physical device that you own. To add a security key, go to Settings → Account and password → Two-factor authentication. → Learn more about hardware security keys

More ways to manage your schedule

Proton Calendar is now available on iPad and also comes with a new compact widget. You can check your schedule at a glance from your home screen and stay on top of events wherever you are.

More ways to send with Proton Mail

Your plan now includes SMTP Submission. This lets you send emails directly from external apps and devices — like a printer, smart home setup, or WordPress blog — using Proton Mail’s trusted IPs and anti-spam protections. → Learn more about SMTP Submission
