Resend Email

What is the Resend Email tool?

The Resend Email tool is a built-in capability in the Agno framework that allows AI agents to send transactional emails via resend api. When added to an agent in Agno Builder, the agent can autonomously decide when to invoke this tool based on the user's request.

This tool requires a RESEND_API_KEY environment variable. Get your API key at resend.com.
