Rock-solid self-hosted email with a feature-rich client.
An opinionated webmail experience on top of your own mail server.

Modern email clients treat your inbox as an infinite stream. hail takes a different approach — an opinionated workflow that keeps you in control of what deserves your attention.

• Your server, your data. Runs on Stalwart, a modern Rust JMAP mail server. No vendor lock-in.
• The Screener. New senders wait at the door. You decide who gets in — and where their mail goes.
• Imbox, Feed, Paper Trail. Three views, zero clutter. Important conversations in the Imbox. Newsletters in the Feed. Receipts and notifications in the Paper Trail.
• Set Aside & Reply Later. Pile up threads you'll get to later. They stay visible, not buried.
• Bubble Up. Schedule threads to resurface — later today, tomorrow, next week.
• Power Through. Triage new mail one thread at a time. Decide and move on.
• Notes on threads. Stick a note on any message. See it in the list, in the thread, in the composer.
• Archive & Search. Archive what you're done with. Full-text search across all views.
• Keyboard-first. Vim-style navigation throughout. j/k, gg/G, d, e, y, m, ., ? — it all works.
• Dark mode. Warm dark palette with system detection or manual toggle.
• PWA-ready. The SPA ships a web app manifest and a conservative service worker: hail can be installed on desktop/mobile, and already-loaded static shell assets remain available offline without caching authenticated mail or API responses.

[ Browser / React SPA ] --> [ hail-api / Rust-Axum ] --> [ Stalwart / JMAP-SMTP ]
                                  |                         ^
                                  | sqlx                    | JMAP EventSource + actions
                                  v                         |
                            [ hail.db / SQLite ] <----> [ hail-worker / Rust-tokio ]

Both hail-api and hail-worker open hail.db directly with sqlx. The browser never talks to Stalwart or SQLite; it only talks to hail-api.

• hail-api — Serves the React SPA, REST API, and WebSocket on a single port. No Node.js in production.
• hail-worker — Background worker for JMAP EventSource subscriptions, screener routing, send-later scheduling, bubble-up timers, and nightly reconciliation.
• Stalwart — Unmodified upstream mail server. hail talks to it via JMAP and the management API.
• hail.db — SQLite sidecar for hail-only state: screener rules, notes, piles, scheduled sends, bubble-ups.

# Clone
git clone https://github.com/your-org/hail.git
cd hail

# Start everything with Podman Compose
cp deploy/.env.example deploy/.env
# Edit deploy/.env with your domain and secrets
podman compose -f deploy/docker-compose.yml up -d

# Open the setup wizard
open http://localhost:8080

The setup wizard creates your first admin account and provisions your domain in Stalwart. After setup, log in and start using hail.

See docs/deployment.md to choose a deployment shape and continue to the right setup guide.

Start here if you want to run hail.

These are for contributors and maintainers; operators do not need them for a normal install.

New senders land here. Approve them into the Imbox, Feed, or Paper Trail — or deny them. Screened-out senders can be unblocked later.

Your important conversations. Sectioned into Bubbled Up, New for you, and Previously Seen (capped, so the Imbox stays finite). Hit Power Through to triage new mail one thread at a time.

Newsletters, notifications, and updates. Read them when you want, not when they arrive.

Receipts, confirmations, shipping updates. They're there when you need them.

Drag threads into piles. Set Aside for "I'll deal with this." Reply Later for "I need to write back." They sit in the corner of every page as a gentle reminder.

Schedule a thread to resurface. "Later today," "tomorrow morning," "next week" — pick a time and forget about it until then.

Markdown-friendly composer with autosave drafts, attachments, reply/reply-all/forward prefill, and send-later scheduling.

Click sender avatars to select multiple threads. Batch archive, trash, set aside, or reclassify in one action.
