Description

πŸ“Š Description
Streamline customer support with a real-time, AI-powered answer engine that detects incoming support emails, classifies intent, identifies the customer’s GEO region, and generates a tailored reply ready to send. πŸ“§

πŸ€– This workflow intelligently adjusts tone and clarity based on region (US, UK, India, Canada, Australia, etc.) and ensures every outgoing message is structured, compliant, and highly contextual. Valid queries receive an automated reply via Gmail and a Slack summary, while non-support messages are flagged for manual review. A perfect automation for scaling support operations with precision and personalization. 🌍⚑

πŸ” What This Template Does
1️⃣ Listens for unread incoming emails using Gmail Trigger. πŸ“₯
2️⃣ Extracts sender, subject, and message snippet for analysis. πŸ”
3️⃣ Uses AI to classify if the email is a real support query. πŸ€–
4️⃣ If valid, predicts the customer’s GEO region (US/UK/India/Canada/EU/etc.). 🌍
5️⃣ Generates a GEO-optimized reply in structured JSON (subject, body, tone). ✍️
6️⃣ Formats the AI response and sends the final email via Gmail. πŸ“€
7️⃣ Sends a Slack notification summarizing the reply, GEO used, and outcome. πŸ’¬
8️⃣ Routes non-query emails to Slack for manual human review. ⚠️
9️⃣ Includes strict JSON validation to avoid malformed AI outputs. πŸ“
πŸ”Ÿ Logs summary details for reporting and operations visibility. πŸ“Š
