AI-Powered Email Auto-Responder with Knowledge Base Integration
detail.loadingPreview
Automate your email replies with an intelligent AI workflow that summarizes incoming messages, classifies their intent, and crafts professional, concise responses. This system integrates an external knowledge base for context-rich answers, ensuring timely and accurate communication without manual effort.
About This Workflow
This n8n workflow brings a sophisticated AI auto-responder to your inbox. It automatically monitors for new emails via IMAP, then intelligently processes them by converting content to markdown and generating a concise summary. An AI classifier categorizes the email's intent, routing it to an advanced AI agent powered by models like DeepSeek. Crucially, the workflow connects to a Qdrant vector store, allowing the AI to query a custom knowledge base (e.g., company FAQs, product info) to formulate accurate, context-aware replies. Before sending, a final AI step reviews and formats the response into professional HTML, adhering to a 100-word limit for brevity, and then sends it back to the original sender, creating a fully automated, intelligent communication loop.
