Honest take: Is Postmark worth it?

Postmark's exceptional deliverability comes from being strict about who they let on the platform—if your use case seems questionable, they'll reject you. This keeps their IP reputation clean and ensures emails arrive. Learn more about email deliverability best practices.

But strict policies and transactional-only focus aren't for everyone. Here's when alternatives make sense:

If you want better DX: Resend

Resend has the best developer experience in email. React Email for templates, modern SDKs, clean API design. If developer experience matters more than Postmark's deliverability focus, Resend is the choice. See our Resend comparison.

Deliverability is good at both—but Postmark's strict vetting gives them an edge on pure inbox placement. Use our DMARC checker and SPF checker to optimize your email setup.

If you need marketing too: Sequenzy

Postmark is transactional only. If you need marketing campaigns, you'll need a second tool. Sequenzy combines both with AI content generation. One platform, one bill, no syncing subscriber data between tools. Check our transactional email guide.

If cost is everything: Amazon SES

At $0.10 per 1,000 emails, nothing beats SES on price at scale. But you're on your own—no templates, no dashboard, no deliverability help. Only choose this if you have engineering resources.

If you need scale: SendGrid

SendGrid handles massive volume reliably. The DX feels dated compared to modern options, but it works. Twilio backing means it's stable long-term. See our SendGrid comparison.

• Postmark: $50+ (tiered pricing)

When Postmark is still the right choice

Stick with Postmark if:

• Deliverability is absolutely critical (password resets, 2FA codes)

• You value their strict customer vetting

• You only need transactional email

• Human support matters to you

Postmark's strict policies are a feature, not a bug. If inbox placement is everything, their approach works. Read our deliverability guide to understand the impact of email reputation, and use our email warmup calculator to plan your transition safely.
