Deploy and Host EmailFlare on Railway

EmailFlare is an open-source, self-hosted email sending platform built on the Cloudflare Email Sending API. It ships an admin UI for managing domains, API keys, templates, and send logs — packaged as a single Docker container with embedded SQLite storage.

About Hosting EmailFlare

EmailFlare is built for minimum infrastructure. A single container bundles the Hono API backend, React admin UI, and embedded SQLite storage via mesahub-core. There are no external databases or message queues to provision. The Railway template pre-configures everything — generated secrets, embedded storage, and a persistent /data volume. All you need to bring are your Cloudflare credentials.

Common Use Cases

• Transactional email for SaaS apps — Send password resets, magic links, order confirmations, and notifications via a simple REST API
• Multi-domain email platform — Manage multiple Cloudflare sending domains and scoped API keys from a single admin dashboard
• Team email infrastructure — Issue per-team or per-service API keys with domain-level scoping; inspect every send in the logs UI

Dependencies for EmailFlare Hosting

• Cloudflare account with Email Sending enabled
• Cloudflare API token scoped to Email Routing (Edit) + Email Sending (Edit)

> Everything else — secrets, storage, volume — is handled by the Railway template automatically.

Deployment Dependencies

• Cloudflare Email Sending — outbound email delivery provider
• EmailFlare Cloudflare token guide — step-by-step token creation with required permissions
• mesahub-core — embedded SQLite storage engine

Implementation Details

The Railway template pre-sets ADMIN_TOKEN, SESSION_SECRET, and MESAHUB_URL with secure generated values and configures a persistent volume at /data. You only need to supply two variables:

CF_API_TOKEN=
CF_ACCOUNT_ID=

Testing without Cloudflare credentials: Create a test API key in the admin UI. Test keys route sends through SMTP (SMTP_HOST / SMTP_PORT) instead of Cloudflare — point them at any SMTP catcher such as Mailpit for safe staging tests.
