Auto-reply to 'Where Is My Order?' Emails with Shopify, Gmail and OpenRouter AI

What This Workflow Does
Automatically handles customer support emails about Shopify orders using AI. When customers email questions like "Where is my order?" or "When will it arrive?", this workflow:

• Receives the email via Gmail trigger
• Classifies the email to identify order-related queries (WISmo - Where Is My Order)
• Retrieves real-time order data from your Shopify store
• Generates a friendly, personalized response using AI
• Sends an automatic reply directly to the customer

Key Features

✅ Smart email classification (handles only order-related queries)
✅ Real-time Shopify order lookup
✅ Natural, empathetic AI responses
✅ Fully automated - no manual intervention needed
✅ Non-order emails are filtered out automatically
