Developer-focused transactional email API with strong validation/inspection tooling, recently repriced upward on its pay-as-you-go tier.

How we test
3.4/5
Saaskly score

Mailgun splits its product into four pieces — Send, Optimize, Validate, and Inspect — aimed at teams that want built-in email verification and deliverability inspection alongside raw sending. A December 2025 price change doubled the pay-as-you-go Flex tier to $2/1,000, weakening its low-volume value proposition relative to competitors.

Pros

  • +Built-in email validation and inspection tools beyond just sending
  • +SPF/DKIM/DMARC configuration handled, shared IP pools plus dedicated IP on Scale
  • +Long-standing developer-API reputation

Cons

  • −December 2025 Flex price doubling makes pay-as-you-go meaningfully less competitive
  • −Shared-pool deliverability described as average, not premium, without a dedicated IP add-on
