## Documentation

# Deploy and Host Hogsend - Posthog Audience Stack on Railway

Hogsend is code-first lifecycle email automation for teams on PostHog + Resend. You define journeys as TypeScript — welcome series, trial nudges, churn recovery — triggered by your PostHog events and sent via Resend, with link/open tracking and one-click unsubscribe built in. This template self-hosts the whole stack on your own Railway project.

## About Hosting Hogsend - Posthog Audience Stack

The template provisions six pre-wired services: an HTTP api (ingestion, auth, the data plane), a worker that runs your durable journeys and sends email, Postgres (TimescaleDB) for the event store and contacts, Redis for the PostHog property cache, and a self-hosted hatchet-lite workflow engine with its own Postgres. Database, Redis, the auth secret, and public URLs are wired automatically. You provide a RESEND_API_KEY, and — once hatchet-lite boots — a HATCHET_CLIENT_TOKEN minted from its dashboard. The worker inherits both from the api, so you set them once, then redeploy.

## Common Use Cases

- Lifecycle email for a PostHog-instrumented product: welcome, activation, and onboarding sequences defined in code
- Trial-to-paid nudges and failed-payment / churn-recovery journeys
- Behavioral + transactional email via Resend, with open/click engagement fanned back out to PostHog, Segment, or Slack

## Dependencies for Hogsend - Posthog Audience Stack Hosting

- A Resend account and API key for email delivery
- A PostHog project as the event source (the primary use case; optional)

### Deployment Dependencies

- Hogsend docs: https://docs.hogsend.com
- Resend: https://resend.com
- PostHog: https://posthog.com
- Hatchet: https://hatchet.run

### Implementation Details 

After deploy, point a PostHog webhook at https://your-api/v1/webhooks/posthog and edit your journeys in TypeScript under src/journeys/. Mint the Hatchet token from the hatchet-lite dashboard (Settings, API Tokens), set it as HATCHET_CLIENT_TOKEN on the api, and redeploy.
