Email you actually own.

An open email protocol built on Nostr. Your address belongs to you, not to a provider that can take it away.

Nmail: The Reference Client

The open-source reference client for the protocol. Built with Flutter for Web, Android, and Linux. Same email UX you know, except your inbox lives on a relay network you control.

  • Cross-platform: Web, Mobile, and Desktop support.
  • Synced: All your folders and settings follow you everywhere.
  • Interoperable: Email anyone, whether they're on Nostr or SMTP (via bridges).
  • Open Source: Transparent and community-driven.

Public discussion, real identities.

Real Nostr notes from real users. Click any name to see the author, or "verify" to see the signed event.

The point is that there's no single point of failure, no centralized control, and your emails are guaranteed to sit encrypted at rest. Seems pretty cool to me. If it becomes production ready, I could potentially switch from Proton. …

Decentralized 'email'. Great leap towards exiting the system.

This is awesome. One question. Can I send to NIP-05 from legacy email? Should I register NIP05 to uid.ovh somehow or how does this work?

The Open Protocol

A set of open standards designed to replace SMTP with a faster, safer, and decentralized relay network.

1301

Kind 1301

The universal email event. A simple JSON structure that carries RFC 2822 email content over the Nostr relay network.

Secure by Default

Uses NIP-44 for encryption and NIP-59 (Gift Wraps) to hide metadata from relays, ensuring total privacy.

Blossom Support

Seamlessly handles large MIME attachments by encrypting and storing them on Blossom servers with hybrid referencing.

Smart Syncing

Uses NIP-32 labels for folders and read states, and NIP-78 for synchronizing settings across all devices.
