Sterna Mail E-Mail App für Android Beschreibung
Sterna Mail is a private, modern email client for Android, built for JMAP — the faster successor to IMAP — with full support for classic IMAP/SMTP too. You pick the protocol when you add an account, so Sterna Mail works with JMAP servers like Stalwart as well as any standard mail provider.
It is private by default, pleasant to use, and fully free software (GPLv3). No tracking, no ads, no analytics, and no Google services required.
Features:
- Built for JMAP — faster sync, less battery and data — plus full IMAP/SMTP
- Multiple accounts (JMAP and/or IMAP/SMTP) with a unified inbox
- Push notifications for new mail without Google services (JMAP push, IMAP IDLE)
- Read, organise, and search your mail — works offline with a local cache
- Conversation threading, configurable swipe actions, folders, flags, archive
- Write, reply, forward, and send — with attachments, drafts, and signatures
- Undo send (a brief hold-back window) and schedule send for later
- Folder management and report-spam
- Privacy by default: remote images and tracking pixels blocked
- Biometric app lock
- Material 3 interface that follows your system light/dark theme
Sterna Mail is open source. The code can be read, audited, and improved by anyone.
