AI Email Responder Agent with Human-in-the-Loop Approval

Unlock Hyper-Efficient Inbox Management with this AI Agent

This AI-driven workflow acts as your personal email assistant. When a new email arrives, the agent first summarizes its content so you can grasp the key points instantly. It then uses an AI model (like OpenAI's GPT-4o Mini) to draft a professional, context-aware reply. Before anything is sent, the draft is emailed to you for a simple, one-click approval. This 'Human-in-the-Loop' system gives you full quality control while automating 90% of the work.

Key Features & Benefits

• AI-Powered Summarization: Instantly understand the gist of any email, no matter how long.
• Intelligent Response Drafting: Generates concise, professional replies based on the email's context and your custom instructions.
• Human-in-the-Loop (HITL) Approval: Maintain complete control. No email is sent without your explicit approval, ensuring brand voice and accuracy.
• End-to-End Automation: From reading the initial email to sending the final approved response, the entire process is automated.
• Universal Email Compatibility: Connects to any email provider that supports IMAP and SMTP (like Gmail, Outlook, etc.).

• An n8n instance (Cloud or self-hosted).
• OpenAI API Key (or a compatible one like DeepSeek) with access to a suitable model (e.g., gpt-4o-mini).
• Credentials for your email account (IMAP for reading, SMTP for sending).
• The approval email must be sent to an address you actively monitor.

1. Import the workflow into your n8n instance.
2. Configure the 'Email Trigger (IMAP)' node with your incoming email credentials.
3. Configure the Language Model (LLM) nodes. The template uses both OpenAI and DeepSeek; connect your preferred model to the 'Email Summarization Chain' and 'Write email' agent nodes and enter your API keys.
4. In the 'Write email' agent, review and adjust the system prompt to match your desired tone and instructions.
5. In the 'Approve Email' node, set the 'To Email' field to the address where you want to receive approval requests.
6. Configure the final 'Send Email' node with your SMTP credentials to enable sending the approved reply.
7. Activate the workflow.
