Pure Developer Focus

No marketing CRM bloat, sales funnels, or SMS cross-sells. Just lightning-fast, reliable transactional email APIs and webhooks.

AI Agent Safety Guardrails

6,000 Free Sends Every Month

Enjoy 6,000 free transactional emails every month forever with zero credit card required, compared to Brevo restrictive 300/day limit.
