Amazon SES vs Mailgun
Comparing pricing tiers, deliverability architectures, and feature support for transactional and marketing senders.
Editorial Verdict
SES is raw infrastructure at $0.10/1k flat with nothing managed; Mailgun is a managed layer ($35/mo incl 50k, then $0.35/1k) selling inbound parsing, validation, analytics, and support on top. If your team can absorb bounce handling, warm-up, and reputation monitoring, SES’s margin advantage is enormous; if email is critical-but-not-core, Mailgun’s tooling pays for itself.
