How Much Does
Mailgun Cost in 2026?
Mailgun is the veteran in this category — been around since 2010, acquired by Sinch in 2021. Their pricing is the most tier-differentiated: Basic $15, Foundation $35, Scale $90 — each jump is substantial. Scale tier including a dedicated IP at $90/mo is notably cheaper than Postmark's $50/mo add-on on top of Platform ($18) = $68 total for similar capability.

Our Verdict
Mailgun's strength is flexibility. The most routing capabilities, the most inbound processing options, the most API surface area. For a backend team building complex email workflows (retry logic, conditional routing, multi-tenant apps), Mailgun's API is the most capable here. Scale tier at $90/mo bundling dedicated IP + SAML SSO + 5000 email validations is genuinely competitive — equivalent Postmark setup would be $18 Platform + $50 dedicated IP + $14 DMARC = $82/mo, and you still wouldn't get 5000 validations. But the tier gaps are aggressive: $15 Basic → $35 Foundation is a 133% jump, and the value unlock (1000 domains, template builder) matters less for most apps than the extra email volume. Foundation at $35/mo with 50k emails is where Mailgun makes sense vs competitors — neither Postmark nor Resend offers an equivalent mid-tier. The dashboard is showing its age — less polished than Postmark or Resend. If you value modern DX, this will feel dated. If you value API flexibility, it's still the most capable.
Pros
- Most flexible API in this comparison — routing rules, conditional sends, inbound processing all at lower tiers
- Scale tier at $90/mo includes dedicated IP — cheaper than Postmark Platform ($18) + dedicated IP add-on ($50)
- Foundation at $35/mo is the only true mid-tier (50k emails) — Postmark/Resend jump straight from 10k to 100k+
- Email validations included in higher tiers — competitors charge $0.80-1.20/100 as a separate add-on
- SAML SSO at Scale tier is enterprise-table-stakes without an enterprise contract
Cons
- Basic-to-Foundation jump is 133% price increase — steep scaling curve for growing apps
- Basic tier overage at $1.80/1k matches Postmark but is 4x Resend Scale rates
- Dashboard UX is visibly older than Postmark/Resend — feels like 2019 software
- Free tier's 100/day limit makes it basically useless for real testing — spike patterns break it
