Resend review
A modern, developer-first email API with React-based templates.
Overview
Resend is a developer-first email API focused on a clean developer experience, reliable delivery, and React Email for building templates as components. It targets transactional and product email rather than visual campaign design, and pairs naturally with code-driven workflows. AI fits here through code generation and agent tooling rather than a built-in campaign generator.
AI approach
Code-first rather than generation-first — AI shows up via React Email components, SDKs, and agent-friendly APIs.
- React Email for composable, code-based templates
- Clean SDKs that pair well with AI code assistants
- Programmatic APIs suited to automated and agent workflows
Strengths
- Excellent developer experience and documentation
- Reliable deliverability infrastructure
- React Email makes templating pleasant for engineers
Considerations
- Not a visual campaign tool for marketers
- No built-in AI campaign generation
- Best paired with a separate marketing layer for non-technical teams
The verdict
The developer's choice for sending email from code — superb DX, though marketers will want a generation layer on top.
