Automated Email Responses with GPT-4O & Supabase Conversation Memory

This n8n workflow lets you delegate inbox management to an AI agent. It automatically replies to emails when a suitable response is found in your knowledge base. If no match is found, the message is forwarded to a human for review. This ensures all replies follow company guidelines and prevent misinformation or misrepresentation.

Use Case Ideal for businesses that receive frequent inquiries about products or services and want to automate responses, freeing up time to focus on core operations.
