Mailastrix Email
All your accounts in one place, with a client that reads ahead — spotting the meeting you need to accept, the deadline you are about to miss, and the message that is not what it claims to be.

- Semantic search — find by meaning, not keyword
Calendar and contacts, in the same app
The meeting your mail is arranging goes straight into your calendar, and the people you write to are already there when you start typing.
- Calendar — month and list views, create and edit events
- Holidays — shown alongside your own entries
- Meeting invites — sent and received by email
- Contacts — company directory typeahead as you address a message
- Harvested contacts — people you have corresponded with, remembered
- Profile photos — synced across your devices
Why it matters
Most of the work that comes out of email is a date or a person. Keeping the calendar and the directory in the same app means neither needs re-typing, and nothing gets lost in the gap between two programs.
Locked to you, on your device
What we do, stated plainly — including what we do not do.
Getting in
- Windows Hello on the desktop
- Fingerprint or Face ID on Android
- PIN fallback, hashed with PBKDF2-HMAC-SHA256 over 210,000 iterations, salted
- Re-locks automatically when your device wakes
Stored on your device
- Mail passwords, AI keys and OAuth tokens encrypted at rest with Windows DPAPI
- On Windows the offline mail cache is encrypted, and its key is DPAPI-protected too
- Nothing is written in plain text that we can avoid
In transit and in the open
- TLS enforced and validated by default
- Protocol logs redacted before they are written
- Single sign-on through Mailastrix Identity
- Diagnostics you export yourself, when you choose
What we do not claim
Mailastrix does not offer end-to-end encrypted mail or chat. Your messages are encrypted in transit and your stored credentials are encrypted at rest, but we can technically access content held on our servers in order to provide the AI features you switch on.
The encrypted offline cache is a Windows feature today. On Android the local cache is not yet encrypted, so rely on your device lock there. If end-to-end encryption is a requirement for you, tell us — it is a decision we would rather make with a real customer than guess at.
Works alongside Chat
One account, one portal, one bill. Add Chat when your team needs calls and meeting notes as well as mail.
