# Resend
Canonical: https://emailagent.tech/tools/resend

Developer-first email API with React Email, strong DX, and growing broadcast and automation features.

Overall score: 8.7

## Developer experience first

Resend targets teams that treat email as infrastructure. The REST API, SDKs, and React Email components make it straightforward to render templates in TypeScript and send from application code. For product-led companies, that model fits onboarding, billing, and feature announcements better than a drag-and-drop marketer UI.

## Broadcasts, automations, and agents

Resend has expanded beyond pure transactional sends into broadcasts and automations with a contact store. The platform added an official MCP server so agents can manage domains, audiences, and sends programmatically. Teams evaluating Brew for agent-native marketing often keep Resend for app-triggered mail, or compare both on whether creation or sending is the bottleneck.
