Postmark vs Resend FAQ

Which one is cheaper?
Postmark starts lower at $15/mo, compared to $20/mo for Resend.
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?
Different approach here. Postmark uses usage-based pricing, while Resend goes with hybrid. That changes the math depending on your team size and usage.
Which one is a better deal?
Depends on what you need. Postmark: Postmark sits mid-pack for transactional email — pricier than bare-bones SMTP APIs but cheaper than enterprise-grade platforms bundling marketing automation. They're clearly chasing developers and product teams who want reliability without paying for bloat they won't use. Resend: Resend sits mid-pack — not the rock-bottom option like raw SMTP relays, but noticeably cheaper to start than Postmark or SendGrid's comparable tiers. They're clearly chasing developer mindshare first (great API, free tier that's actually usable) and letting usage-based pricing capture revenue as those developers' apps scale into real businesses.
