Standards-based mail

Connect one or more IMAP and SMTP accounts without changing mail providers.

Private by default

Run the web app, worker, and PostgreSQL database in infrastructure you control.

OpenPGP built in

Sign, encrypt, verify, and decrypt cleartext, detached, and PGP/MIME messages.

Single-owner security

Use a password, passkeys, GitHub, Discord, OpenID Connect, or a combination.

Background processing

Mail sync, sending, cleanup, AI classification, and notifications run outside web requests.

Automation ready

Integrate through the authenticated REST API or the built-in MCP transports.

How mail runs

A production installation has two application processes. The web process serves the SvelteKit application and HTTP APIs. The worker process owns mailbox synchronization, outgoing delivery, cleanup, and other background jobs. Both processes share PostgreSQL and the same configuration secrets.

Start with the getting started guide, browse the feature pages, or review the architecture before planning a production deployment.
