Choose Postal.
If you want to own your data, save money, and avoid vendor lock-in, Postal is open source and community-driven.
What Actually Matters
No fluff — just the differences that affect your decision
Postal is open source (MIT). Mailgun is closed. If vendor lock-in keeps you up at night, this is the deciding factor.
Postal supports self-hosting via Docker. Mailgun is SaaS-only — convenient, but you're renting, not owning.
Postal has the bigger crowd: 16.9k stars vs 0. More contributors, more integrations, more momentum.
Postal is built in Ruby — you can read the source, contribute, or fork it. Mailgun is closed-source, so you're trusting their engineering.
Try both — most offer free tiers. The right pick depends on your stack size, team, and tolerance for DevOps.
