Description

Aster Mail keeps your messages and personal information secure and private. It is a free encrypted email app with end-to-end encryption, PGP, email aliases, and zero ads.

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.
- Your mailbox is zero access and zero knowledge, so your mail is encrypted at rest and in transit.
- Quantum-safe email encryption protects you today against harvest now, decrypt later attacks.

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.
- Email aliases work as disposable, burner, and throwaway addresses for signups.
- If you ever need more, paid plans start only at $2.99 a month.
- Paid plans add custom domain email for your business, your family, or your own name.

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.
- Schedule send, undo send, snooze, signatures, attachments, and contacts are all built in.
- Add your existing IMAP, SMTP, and POP3 accounts and read every inbox in one mail app.
- Lock the app with a PIN, biometrics, or a passkey, and turn on two-factor authentication.

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.
- Tracking protection blocks spy pixels, read receipts, and remote images before they load.
- The spam filter and phishing protection keep scam mail and junk out of your inbox.

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.
- You can also download the signed APK straight from our site instead of a store.

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.
- Import your old mail in a few taps and switch to a private email address without losing a message.
- 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.

The same secure email everywhere
- Aster Mail also runs on Windows, macOS, Linux, and the web, and your encrypted mailbox syncs across all of them.
- Aster Bridge connects your mailbox to any desktop email client over IMAP and SMTP.

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.
