Everything you need. Encrypted.

One platform for secure communication and organization — without compromising your privacy.

Encrypted mailbox

Full-featured email with folders, signatures, PGP support, and webmail — all end-to-end encrypted.

Encrypted calendar

Scheduling with invitations, recurrences, drag & drop, and ICS import — compatible with Outlook, Gmail, and Apple Mail.

Encrypted contacts

Address book with PGP key management and VCF import — encrypted in your vault.

Disposable addresses

Up to 10,000 email aliases that hide your real address. The original since 2002 — trusted by over 90,000 users.

AI integration. Your way.

Three ways to use AI with your mailbox — from the browser to your own GPU infrastructure.

Local AI in the browser

AI assistant directly in the browser via WebLLM — no server round-trip, no data leakage. Your emails never leave your device. Translate, summarize, compose — all locally.

Cloud agents (OpenClaw)

Autonomous AI employees with their own mailbox and identity. Read, reply, and manage emails around the clock — like an employee, just without breaks.

MCP interface

Connect your own AI systems — Claude Code, Cursor, or your local LLM on Mac Studio / Nvidia DGX. Open protocol, own mailbox, disposable addresses included.

Post-quantum encryption. Now.

Your emails from today must not become tomorrow's vulnerability.

Hybrid KEM

ML-KEM-1024 combined with X25519 — even quantum computers cannot break this encryption.

Zero-knowledge

Your password never leaves the browser. We cannot read your emails — even if we wanted to.

Shamir Secret Sharing

Three keys secure your mailbox: password, passkey, recovery key. Any two are enough to unlock.

Perfect Forward Secrecy

Every request uses unique keys. An intercepted request is worthless for all others.

"Harvest Now, Decrypt Later"

Intelligence agencies store encrypted data today to decrypt it with quantum computers tomorrow. Not with us.

For everyone who means it.

Whether personal or business — your communication deserves real protection.

Personal use

Protect yourself from tracking, spam, and nosy providers. Your mailbox belongs to you.

Business

Custom domains, team management, compliant archive, and AI agents — enterprise security without compromise.

Journalists

Source protection through zero-knowledge. Not even we know who you communicate with.

Activists

Post-quantum encryption protects your communication even against state-level surveillance.

Doctors & lawyers

Professional secrets deserve maximum protection. GDPR-compliant, encrypted, hosted in Germany.

How we stand out.

Frequently asked questions

What is post-quantum encryption?
Post-quantum encryption uses algorithms that cannot be broken even by future quantum computers. Aionda Mail uses ML-KEM-1024 combined with X25519 (Hybrid KEM) — the current NIST standard.
What does zero-knowledge mean?
Zero-knowledge means the server never has access to your unencrypted data. Your password never leaves the browser, emails are encrypted client-side. Even we as operators cannot read your content.
How is this different from Tuta or Proton Mail?
Aionda Mail offers post-quantum encryption, disposable email addresses, AI agents, and shared folders with end-to-end encryption — features that neither Tuta nor Proton Mail offer in this combination.
Can I use my own domain?
Yes. Plus members can connect custom domains with SPF authentication. Your emails are received and sent under your own domain.
What happens if I forget my password?
Thanks to Shamir Secret Sharing, you have three independent access paths: password, passkey (fingerprint), and recovery key. Any two are enough to unlock your mailbox. A classic password reset is deliberately impossible — that's the proof that we cannot read your data.
Is Aionda Mail GDPR compliant?
Yes. Aionda Mail is operated by Aionda GmbH in Stuttgart, Germany. All servers are located in Germany. The zero-knowledge architecture additionally protects your data technically — even in case of a data breach, the data would be worthless.
