## The Hook

Postal is the self-hosted mail server when Resend is hosted API and Listmonk is newsletters.

## What's Good

MIT. SMTP + HTTP API mail delivery you run. Full control of queues, IPs, and logs. Docs live via GitHub (postalserver.io 301s — use the repo). No per-seat tax on the core.

## The Catch

Self-hosted mail delivery SMTP+HTTP API — not Resend hosted tx email, not Plunk Node email, not Listmonk newsletter app. You own deliverability and IP reputation. Distinct from Resend, Plunk, and Listmonk.

## Verdict

MIT self-host mail. Free to run; deliverability is your ops.
