# Resend Skill

The Resend skill enables AI agents to send emails through the Resend API using our official recommendations. It provides a streamlined interface for sending single and batch emails with built-in error handling and retry logic.

## Installation

This skill is part of the [resend-skills](https://github.com/resend/resend-skills) repository, which also includes the [Agent Email Inbox skill](/guides/build-with-ai-agent-email-inbox-skill) for secure inbound email processing. When you run the install command, you'll be prompted to choose which skills to install.

```bash theme={"theme":{"light":"github-light","dark":"vesper"}}
npx skills add resend/resend-skills
```

Clients that support the [Agent Plugins](https://agent-plugins.org) spec can install the same repository as a plugin. That install adds these skills and the [remote MCP server](/guides/resources-mcp-server) together. The [MCP server docs](/guides/resources-mcp-server#remote-mcp-server) list the install command for each supported client.
