Aster Mail keeps your messages and personal information secure and private.

Aster Mail is built around end-to-end encryption, which means you don't have to trust us with your data, your messages, or your keys. Only you can read your inbox, and we can't even if we tried.

End-to-end encryption
- No one, including us, can read your private messages.
- Messages between Aster users are protected with ML-KEM-768 post-quantum encryption.

Aster Mail is forever free
- The free plan is a real free plan with 10 GB and full encryption included.
- You can create multiple aliases to keep your personal identity hidden.
- If you ever need more, paid plans start only at $2.99 a month.

Fast, simple, and easy to use
- It's as smooth as Gmail or Outlook, just without any surveillance.
- You get push notifications, dark mode, search, swipe gestures, folders, labels, filters, and multiple identities.

No trackers, no ads, ever
- You can sign up with just a user name and password without handing over any personal information.
- Your data will never be sold, shared, or monetized.

Open source and auditable
- All of our code is open source on our GitHub under AGPL v3 for you to audit and check.
- You can read it, audit it, or submit a pull request yourself.

Standard OpenPGP for everyone else
- When you email somebody on Gmail, Outlook, or Proton Mail, we use OpenPGP with RSA-4096 and automatic key discovery to encrypt those messages.
- Your keys are portable and work with any other PGP client, such as Thunderbird or GPG.
- If you ever decide to leave Aster, you can take your mail and keys with you. We do not believe in vendor lock-in.

Located in Germany
- Our servers are located in Falkenstein, Germany under Strict GDPR and Privacy Laws.
- Your mail is covered by EU data protection law instead of US subpoena reach.
- We publish and update a signed Warrant Canary to keep you updated, as well as a transparency page.

Built to last
- Aster is run by a small, motivated, independent team, and we are not chasing acquisition or venture capital investors.
- We're building an email service that exists and is charging a fair price so we can keep innovating.
