Postmark gives 100 emails/mo (no expiration), which is why teams compare it in 2026. The strongest Postmark alternatives are Resend, Mailgun, and Brevo: Resend offers the best Next.js developer experience with a 3,000/mo free tier, Brevo has the largest free tier, and Amazon SES is cheapest at $0.10 per 1,000.

What you actually pay on Postmark today, for context. Source: https://postmarkapp.com/pricing.
Postmark is a solid transactional email provider, but teams put it up for comparison for concrete reasons: small free tier (100/mo) and not for marketing/bulk campaigns. Its strengths are industry-leading deliverability and speed and separate transactional / bulk message streams, so whether an alternative is worth the switch depends on which trade-off actually affects your project.
Postmark is free up to 100 emails/mo (no expiration), then paid plans run $15/mo for 10,000 and $16.5/mo for 10,000, with overage from $1.80 / 1k; dedicated IP: From $50/mo (requires 300,000+/mo). Best when deliverability matters most. In Next.js, use the postmark SDK from a Route Handler.
Among the alternatives, Resend (3,000 emails/mo (100/day) free, from $20/mo) for best-in-class developer experience (React Email, type-safe), Mailgun (100 emails/day (~3,000/mo) free, from $15/mo) for flexible routing and inbound processing, and Brevo (300 emails/day (no time limit, ~9,000/mo, shared with campaigns) free, from $9/mo) for generous no-expiry free tier (300/day). On Next.js specifically, Resend is the smoothest migration thanks to its type-safe SDK and React Email templates.
Pick by priority: Brevo if a generous always-free tier matters most, Postmark if inbox placement for receipts and password resets is critical, and Amazon SES for the lowest per-email cost at scale. All figures were verified against each vendor's pricing page on 2026-07-05.
