Enable AI agents to send and receive emails via API or MCP protocol. Automate communications in coding assistants, terminals, and applications.
What is Resend Agents?
Resend Agents is a communication infrastructure designed to allow artificial intelligence agents to send and receive emails autonomously. Unlike traditional email interfaces built for human interaction, this tool optimizes communication between AI and the email protocol, enabling agents to manage inboxes, contacts, and logs using natural language. It is a technical solution geared toward developers looking to integrate messaging capabilities into automated workflows and intelligent applications.
The core technology behind the tool is powered by the Model Context Protocol (MCP). By connecting an agent to the Resend Agents MCP server, it gains native access to the entire platform to execute actions without needing to program every interaction from scratch. In addition to the MCP protocol, it offers support for REST APIs, SDKs, and a professional CLI, ensuring compatibility with any execution environment, whether on a local computer or cloud servers.
Resend Agents integrates natively with today's leading development and software creation ecosystems:
- Code editors and programming agents: It is compatible with Cursor, Claude Code, GitHub Copilot, Codex, and Zed, allowing users to send emails directly from the editor or terminal via commands or natural language.
- App-building platforms: Tools like v0, Replit, Lovable, and Bolt can use the Resend API key to immediately equip applications with transactional email and user management functionalities.
- Autonomous and personal agents: It provides email "skills" to agents like Devin, Grok Bot, and Hermes, enabling them to act as proactive communication managers that can read and process messages.
One of the tool's most powerful features is inbound email handling. The system routes incoming emails to a specific endpoint, allowing the AI to read user replies and act accordingly in an automated fashion. Additionally, it facilitates the creation of email templates using React Email, allowing agents to generate professional visual designs with the same logic they use to write the rest of the application code.
This infrastructure allows developers to scale their AI projects from initial stages to high-volume production environments. By centralizing audience management, delivery logs, and automations into a single programmatic interface, Resend Agents eliminates technical friction when integrating communications for agentic AI applications.
