Mailgun Pricing Plans & Tiers
Transactional email API for developers with deliverability tools
Pricing last verified: March 16, 2026
Pricing Analysis
Mailgun's tiering (Free 100/day test tier, Basic $15/month, Foundation $35/month, Scale $90/month, Enterprise custom) targets developers building email applications (transactional, not marketing campaigns). The Free tier (100 emails/day, test-only limit) removes adoption friction vs. AWS SES' free tier (3K/month) while positioning Mailgun as 'developer-first'.
Basic tier ($15/month, no daily limit, monthly overages, APIs) is Mailgun's SMB entry—developers and startups testing email integrations land here. The Basic-to-Foundation jump (+$20, +133%) is steep, suggesting Foundation tier adds significant capabilities (domains, SSO, validations).
Mailgun's per-email overage costs (not published in tier data) create hidden pricing complexity vs. Resend's flat tiers or SendGrid's published per-tier limits. This opacity is deliberate: Mailgun captures users with cheap base tier, then monetizes through overages when volume grows.
Strengths
- Free tier (100/day test tier, no credit card) removes activation friction for developers evaluating email APIs, competing with SendGrid's free tier while maintaining lean product.
- Basic tier ($15/month, no daily sending limit) removes the artificial daily caps that other platforms impose, appealing to teams with variable sending patterns (bursty traffic).
- Foundation ($35/month) through Scale ($90/month) tiers offer clear upgrade path with incremental feature additions (domains, validations, SSO), creating rational pricing progression.
Considerations
- Free tier (100/day test limit) is extremely restrictive for multi-user testing teams—a 5-person development team testing email integrations quickly exhausts daily limit.
- Overage pricing (not published per tier) creates hidden cost risk—teams uncertain whether Basic tier includes overage costs or charges per-email, creating billing surprise risk.
- Foundation tier's 1K custom domains and Scale tier's 5K validations suggest teams uncertain whether they need these features, forcing sales conversations rather than transparent feature comparison.
SaaS platforms and startups sending transactional email notifications at scale, valuing API-first development experience and transparent tiering vs. Mailgun's simplicity.
Mailgun's Basic tier ($15/month) is cheap entry for transactional email, but lack of published overage costs creates uncertainty vs. Postmark's transparent per-email pricing.
