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).
