This n8n workflow automates the process of handling incoming emails, generating AI-driven replies, and logging all interactions in Google Sheets for continuous improvement and record-keeping. When an email from specific recipients is received, it triggers the extraction of the message content, which is then sent to OpenAI’s GPT model to craft a reply. This reply is sent back to the email sender with an embedded feedback link, allowing recipients to rate the usefulness of the response. All email data, GPT responses, and feedback ratings are systematically stored in Google Sheets, which can also be auto-created if missing. Additionally, the workflow supports fine-tuning by capturing feedback data for model adjustments. The setup is practical for customer support, automated email autoresponses, and continuous AI model improvement.
