What you give up vs SendGrid
- You are responsible for IP reputation, warmup, and deliverability
- Requires MariaDB, RabbitMQ, and DNS/DKIM configuration to run
- No marketing-campaign UI — it is a delivery engine, not a newsletter builder
- Less hand-holding than managed providers for spam/blocklist issues
What you gain
- • Full data ownership — self-host Postal on your own infrastructure.
- • No per-seat SaaS bill (SendGrid: per-email costs at scale).
- • Open-source code you can audit and extend (MIT).
