About this workflow
This workflow automates customer email support by combining Gmail, AI classification, and a knowledge base to provide instant, accurate, and friendly responses. It’s designed for businesses that want to improve customer satisfaction while reducing manual workload. --- 🚀 How it Works 1. Gmail Trigger The workflow listens for new incoming Gmail messages. 2. Text Classification Each email is classified using AI as either Customer Support or Other. - If it’s Other, the workflow stops. - If it’s Customer Support, the email continues to the AI agent. 3. AI Agent with Knowledge Base The AI agent: - Reads the customer’s message. - Searches the Pinecone Knowledge Base for FAQs and policies. - Generates a helpful, polite, and detailed reply using an OpenRouter model. - Signs off as Mrs. Helpful from Tech Haven Solutions. 4. Reply to Gmail The drafted email is automatically sent back to the customer. --- 💡 Value - ✅ Save Time – No more manual triaging and drafting of replies. - ✅ Consistency – Every answer is based on your own FAQ/policies. - ✅ Customer Satisfaction – Fast, friendly, and accurate responses 24/7. - ✅ Scalable – Handle higher email volume without scaling headcount. --- 🔑 Credentials Needed To use this workflow, connect the following accounts: - Gmail OAuth2 → for receiving and sending emails. - OpenRouter API → for text classification and AI-generated replies. - OpenAI API → for embeddings (to connect FAQs with AI). - Pinecone API → for storing and retrieving knowledge base content. --- 🛠 Example Use Case A customer writes: > “Hi, I placed an order last week but haven’t received a shipping confirmation yet. Can you check the status?” The workflow will: 1. Detect it’s a support-related email. 2. Retrieve order policy information from the knowledge base. 3. Generate a friendly response explaining order tracking steps. 4. Automatically reply to the customer in Gmail. --- ⚡️ Setup Instructions 1. Import this workflow into your n8n instance. 2.
