Resend
Developer sending API
Developer-first email API with React Email, strong DX, and an official MCP server for agent control of sends and domains.
Délivrabilité
Resend automates DKIM and SPF when you add a domain and documents DMARC alignment steps clearly. The platform is optimized for transactional and product mail with strong default reputation on shared infrastructure. Marketing broadcasts still need list hygiene and gradual volume ramps like any ESP.
Rendu
React Email components compile to table-based HTML tuned for modern clients. You own the template code, so Outlook fixes are your responsibility. Resend's preview tools help, but Litmus or Email on Acid remain the gold standard for pre-send checks.
Points forts
- Clean REST API and SDKs
- React Email ecosystem
- Official MCP server for agents
