Send & Receive Emails with Replit

Replit builds apps and agents from natural-language prompts. Enable the AgentMail integration and anything it builds gets an email inbox of its own to send, receive, and reply from.

What you will need

A Replit account.
An AgentMail API key, if you connect with a key. Generate one here.

Connect AgentMail

Open Settings from the workspace menu (bottom-left), go to Integrations, and search AgentMail. Pick how you want to authenticate:

Use an API key — enable the AgentMail integration (the first result), paste your API key, and click Configure.
Use OAuth sign-in — choose the MCP option instead and sign in to AgentMail when prompted. No API key needed.
