Resend vs Postmark
for indie hackers.
Resend by default — generous free tier, modern API.
What this actually means for indie hackers.
For indie hackers, Resend is the clear default in 2026. The free tier (3,000 emails/month) covers most pre-launch products. The React Email integration produces beautiful emails without HTML hell. The API is modern and the deliverability is strong. Postmark is still excellent for transactional email but the free tier is non-existent and the developer experience is slightly less modern. Indie hackers picking Postmark in 2026 are usually on it from years ago.
indie hackers-specific gotchas
- Resend free tier limits matter as you scale
- Domain verification is required before production sends
- React Email adds a learning curve but pays back quickly
- Resend's webhook reliability is excellent
- Both have transactional / broadcast separation
An indie hacker ships their SaaS with Resend's free tier handling all transactional email for the first 6 months. Total cost: $0. After 3,000 emails/month they upgrade to Pro at $20/month — still cheaper than Postmark's entry tier.
