Description

This template demonstrates an AI-powered email automation system for Re:amaze, summarizing and responding to customer inquiries using a structured knowledge base to ensure accurate and consistent replies.

šŸ”¹ Ideal for:
Customer support teams handling high volumes of email queries (e.g., e-commerce, SaaS)
Businesses looking to automate SOP-based responses with AI while integrating actions like order lookup or issue logging

What this workflow does
Fetches incoming customer emails from Re:amaze
Filters only customer messages (ignores agent replies)

Generates a response using AI based strictly on SOP
Sends reply back to the customer automatically

Key Features:
Prevents duplicate replies using deduplication logic
Ensures responses follow SOP (reduces hallucination)
Scalable for high-volume email handling

Re:amaze API access (for fetching & replying to conversations)
AI model (e.g., OpenAI / Gemini configured in n8n)
SOP knowledge base (Google Sheets or Code tool)
