Zero-knowledge email for developers

The inbox
built for privacy.

End-to-end encrypted by default. A real API. A CLI. No surveillance, no dark patterns. Your data is yours — mathematically, not just legally.

What's included
🔐
01
Zero-Knowledge Encryption

Keys derived locally. We never see plaintext — not by policy, by architecture. Nothing to hand over, even under subpoena.

02
Full REST & IMAP API

SDKs in Node, Python, Go, Ruby. Complete OpenAPI spec. Every operation the web UI does, your code can do too.

03
CLI — gz

Inbox management, alias creation, webhook tailing — all from the terminal. Your stack, your workflow.

@
04
Ephemeral Aliases

Disposable addresses with configurable TTLs. When they expire, they're gone — along with everything sent to them.

05
Webhooks & SMTP Relay

Pipe incoming mail into your app. Transactional email without managing your own MTA. Real-time delivery logs.

06
Self-Hostable

Full stack on your own infra. Docker and Kubernetes support. MIT licensed. Your keys, your rules.

Our position

Most "private email" is a promise in a ToS. Gazelle Mail is a proof in a codebase.

Developers deserve an email layer that integrates with their stack, respects their intelligence, and doesn't surveil them in exchange for convenience.

You own your data. Export anytime. Self-host if you want. We'll never hold your inbox hostage.
