Tool profile
Email delivery service for transactional messages, sending infrastructure, and developer APIs.
Applications sending millions of transactional notifications
Mailgun (Sinch) is an API-first sender for SaaS notifications, receipts, and operational mail, with optional validation and inbound routing. It competes on flexible event webhooks, logs, and SMTP compatibility for legacy systems.
The public pricing page (mailgun.com/pricing, March 2026) lists Free at $0/month with 100 emails/day, 1 custom domain, 1 day log retention, and ticket support. Basic starts at $15/month with 10,000 emails/month included and overages from about $1.80 per 1,000 emails. Foundation offers a one-month free trial then $35/month with 50,000 emails/month included, 1,000 domains, longer logs (5 days), and overages from about $1.30 per 1,000 emails (tier steps down at higher volumes on the public table). Scale trials one month then $90/month with 100,000 emails/month included, SAML SSO, 5,000 email validations, dedicated IP pools, 30-day logs, and overages from about $1.10 per 1,000 emails with additional volume discounts on the ladder.
Email validation is priced per hundred validations on Foundation+ with tiered rates. Dedicated IPs can be added (public FAQ cites about $59/IP/month for additional IPs on some plans).
Compare Postmark for strict transactional positioning; compare SendGrid inside Twilio bundles; compare Resend for minimalist developer onboarding.
Quick fit
Editorial take
Start by matching daily cap (free) vs monthly bundles (paid)—the free tier is 100/day, not 10k/mo. Foundation vs Scale is about SSO, validations, IP pools, and log retention, not just message count. Overage ladders change by tier—import the live table into finance models. For alternatives, SendGrid adds marketing UI; Postmark simplifies transactional; SES minimizes transport cost.
