AI Email Auto-Reply with ChatGPT & Google Sheets Logging

This n8n workflow revolutionizes email management by using OpenAI's ChatGPT to generate intelligent replies to emails received from specific recipients. Upon triggering from the 'On email received' node, it extracts the email body, crafts a contextual response via the OpenAI node, and sends a reply including a unique feedback link. All data—the original email, GPT response, and later feedback—is automatically saved to a dynamically created or existing Google Sheet, enabling easy tracking and analysis.

A secondary flow activates via the 'On feedback given' trigger when users click the feedback link to rate the GPT response positively or negatively. This feedback is appended to the corresponding row in the Google Sheet, creating a valuable dataset for future model fine-tuning. Prerequisites include OpenAI and Google credentials, making setup straightforward for n8n users.

Benefits include massive time savings on email responses, improved response quality through AI, and built-in mechanisms for continuous improvement via feedback loops. Ideal use cases span sales CRM (e.g., responding to leads), customer support, or any high-volume email scenario in business proposals, where logging interactions enhances personalization and performance metrics.
