Most encrypted email services leave your subject lines and metadata exposed and unencrypted. Aster Mail encrypts everything, including subject lines, with quantum-safe ML-KEM-768 encryption. Your keys are portable and work with GPG and Thunderbird, with no vendor lock-in. Aster is open source under AGPLv3, hosted in Germany with a generous free plan. Try it free at astermail.org
Hey Product Hunt! We're Findley, Athanasios, and Andrés, founders of Aster Mail.
We have been building an unprecedented end-to-end encrypted email service where we, by design, cannot read your mail. No other encrypted email service has post-quantum cryptography in production that works with any email provider, not just their own users. Client-side encryption with post-quantum cryptography, zero-access architecture, fully open source under AGPL v3, servers located in Germany.
We built Aster Mail because we wanted end-to-end encrypted email that's actually private. All encryption and decryption happens client-side. We encrypt email content, subjects, contacts, folder structure, search indices, timestamps, and attachment data locally before anything touches our servers. Minimal routing metadata (sender/recipient addresses) is required for SMTP delivery, but we encrypt everything we can beyond that. On top of standard PGP, we include post-quantum cryptography by default, protecting against store-now-decrypt-later attacks.
Aster's feature set includes things like: free 10GB of storage, free aliases & ghost aliases (auto-generated anonymous addresses), free custom domains, encrypted contacts with device syncing, burn-after-read messages, scheduled send, email snooze, encrypted search, subscription management, and much more.
Longer term, Aster is building a full encrypted communications suite with drive, chat, and authenticator.
