SendHQ vs Postmark — why SendHQ wins
A developer-first email API: send and receive transactional mail, verify domains, track delivery and bounce events, route inbound mail, and control it all with scoped API keys.

Where Postmark falls short
- Bad experiences reported by users
- Scam complaints surface in reviews
- Slow response times
- Free tiers are small (100s/day)
Why SendHQ wins
- Inbound and outbound mail in one product instead of two vendors
- Scoped API keys, so an agent or a service gets only the permissions it needs
- Delivery and bounce tracking included on the entry plan
