Automated Email Response with AI and Human-in-the-Loop

This n8n workflow automates the process of handling incoming emails, summarizing their content, generating professional responses, and incorporating human review for quality control. It begins with an IMAP email trigger that monitors a designated inbox. The email content is then converted to Markdown format for improved processing and summarized using AI language models (GPT-4 and DeepSeek), distilling the main message into a concise summary. Based on this summary, an AI generates a draft reply that aligns with professional standards. Before sending, the workflow includes a human-in-the-loop step where a reviewer can approve or modify the response. If approved, the reply is sent via email, completing an automated yet controllable communication loop, ideal for customer support or business correspondence automation.
