🤖 AI Email Agent — AgentMail + OpenAI

An AI-powered email agent that can send, receive, and reply to emails intelligently using GPT-4.

Built with AgentMail — the email API for AI agents.

What it does

1. Creates its own email inbox — your agent gets a unique email address
2. Receives emails — processes incoming messages in real-time via webhooks
3. Replies with AI — uses GPT-4 to generate contextual responses
4. Manages threads — maintains conversation context across email chains

Setup

1. Get a free AgentMail API key at console.agentmail.to
2. Get an OpenAI API key at platform.openai.com
3. Add both as Replit Secrets:
   • AGENTMAIL_API_KEY
   • OPENAI_API_KEY
4. Click Run!

How it works

• On startup, the agent creates a new email inbox
• A Flask server runs to receive webhook events from AgentMail
• When someone sends an email to the agent's inbox, it:
  • Extracts the new content (strips quoted replies using extracted_text)
  • Loads the full thread for conversation context
  • Generates a reply using GPT-4
  • Sends the reply back via AgentMail
