Mailgun vs Postmark FAQ
- Which one is cheaper?
- They both start at the same price — $15/mo. The difference is in what you get at each tier.
- Can I use either one for free?
- Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.
- How do they charge?
- Both use a usage-based model, so the comparison is straightforward — it comes down to features and limits at each price point.
- Which one is a better deal?
- Depends on what you need. Mailgun: Mailgun sits mid-pack in the transactional email space — pricier than bare-bones API-only competitors but cheaper than enterprise-grade ESPs, aiming at developers and growing SaaS teams who want reliable deliverability without paying for a full marketing suite. The free month on Foundation and Scale is clearly there to nudge fence-sitters into the paid tiers before the meter starts running. Postmark: Postmark sits mid-to-premium in transactional email, priced above bare-bones SMTP relays but below enterprise-grade platforms with heavy marketing-automation bolt-ons. They're not competing on rock-bottom per-email cost — they're selling deliverability reputation and simplicity to teams who got burned by their emails landing in spam elsewhere.
