This n8n workflow automates end-to-end customer support email handling by intelligently classifying incoming Gmail messages and routing them based on intent, complexity, and authenticity. It uses AI to distinguish between real customer queries and promotional noise, categorize requests (billing, technical, etc.), and determine whether a response can be generated automatically or requires human intervention.

For simple queries, the system drafts a professional reply using predefined FAQs and guardrails, ensuring consistency and compliance. Complex or sensitive emails are escalated by creating structured tickets in tools like Trello or helpdesk systems, with detailed AI analysis attached. Real-time Telegram notifications keep teams informed, while fallback error handling ensures no customer query is missed, making the workflow robust, scalable, and production-ready.
