Deploy and Host

Self-hosted newsletter and mailing-list manager (listmonk v6.2.0, AGPL-3.0) with a PostgreSQL 16 companion. One-click deploy: the form has zero fields — the Postgres password is auto-generated and the app is auto-wired over the private network. First boot installs the schema; the setup wizard on the public URL creates your superuser.

About Hosting

Services: listmonk (Go binary) + postgres (PostgreSQL 16)
Volumes: 2 — Postgres data at /var/lib/postgresql/data, app uploads at /data (listmonk-data)
Memory at rest: ~30–60 MB app, ~100–200 MB Postgres
Healthcheck: GET /health → 200 (public, unauthenticated)

Why Deploy

Own your mailing list instead of renting it per subscriber. Listmonk gives you unlimited lists and subscribers, a visual campaign editor, scheduling, bounce handling, and open/click analytics — you only pay Railway usage plus your SMTP provider.

Common Use Cases

Newsletters for blogs, products, and communities
Launch announcements and drip campaigns
Bulk mail via the REST API (digests, notifications)
Multi-list audiences with segments and custom attributes

Deployment Dependencies

Railway Hobby plan or higher (Postgres volume needs a few GB)
After deploy: create the superuser in the setup wizard, then configure SMTP in Settings → SMTP before sending. SMTP lives in the database, not in env vars.

Environment reference (condensed): LISTMONK_db__host = ${{postgres.RAILWAY_PRIVATE_DOMAIN}}, LISTMONK_db__password = ${{postgres.POSTGRES_PASSWORD}}, POSTGRES_PASSWORD = ${{secret(32)}} — all auto-wired. Baked into the image: LISTMONK_db__port=5432, LISTMONK_db__user=listmonk, LISTMONK_db__database=listmonk, LISTMONK_db__ssl_mode=disable, LISTMONK_upload__filesystem__upload_path=/data/uploads (volume-persisted). The entrypoint also rewrites two DB-seeded settings listmonk loads over env vars: upload.filesystem.upload_path → /data/uploads and app.root_url → the public domain. Optional, set later: LISTMONK_ADMIN_USER + LISTMONK_ADMIN_PASSWORD (skip the web wizard), LISTMONK_ADMIN_API_USER.
