Automated AI-Powered Gmail Customer Support Workflow

This n8n workflow streamlines customer support by automatically monitoring a Gmail inbox for new inquiries, classifying emails, and generating contextually relevant responses using OpenAI’s GPT-4. When a customer email arrives, the workflow employs the Inquiry Filter node to distinguish genuine inquiries from spam or promotional content. Relevant FAQ data is retrieved from a Google Sheet through the Google Sheets Context Retrieval Tool, which provides the knowledge base for the AI response generator. The Reply Generator AI Agent then crafts a professional, friendly reply that addresses specific questions based on predefined FAQs. The response is automatically sent back to the customer via Gmail, and all interactions—including the original message, AI-generated reply, and timestamps—are logged into a Google Sheet for tracking and improvement. This workflow enables 24/7 automated support, reducing human workload and ensuring prompt, consistent customer communication.
