Automate Gmail Email Categorization & AI Response Generation

This n8n workflow transforms Gmail into an AI-powered email manager. It uses a webhook trigger (with Gmail push notifications via Pub/Sub) to monitor incoming emails in real-time. The email content is analyzed by GPT-4 or similar AI models to automatically categorize messages, identify key intents, and generate context-aware responses. Based on categories and content, it can trigger actions like sending replies, forwarding emails, or creating tasks.

Key benefits include massive time savings by eliminating manual sorting and responding, reduced errors through AI accuracy, and scalability for high-volume inboxes. It's ideal for professionals handling customer inquiries, sales leads, or support tickets, ensuring nothing slips through the cracks while maintaining a professional tone in replies.

Use cases span business communication, such as travel agencies categorizing driving/logistics emails (bookings, routes, delays), customer service automating responses, or executives triaging urgent messages. Setup requires Gmail API OAuth, AI API keys, and n8n credentials, with detailed guides for Google Cloud Console and services like OpenAI or Claude. Advanced features like custom classification rules make it adaptable to any domain.
