Show HN: Event-Driven Email Assistant with Node-Red and DeepSeek AI (github.com)

A new Node-RED flow and npm package—node-red-contrib-email-analysis-deepseek—has been released and added to the Node-RED Official Flow Library. It integrates an IMAP listener (Gmail support with OAuth2) with the DeepSeek Chat API to automatically ingest incoming emails, extract sender/subject/content, perform intent recognition, surface key facts (time, place, people), and generate targeted reply suggestions. The project includes English and Chinese flows, a modern web dashboard for real-time monitoring and notifications, history tracking (configurable retention, default 30), and tools for statistics, batch notification management, and automatic cleanup. This is significant because it packages event-driven email automation and AI analysis into a ready-to-deploy Node-RED node, lowering the barrier for teams to add contextual NLP, routing, and reply automation into existing workflows without heavy engineering. Technical highlights: IMAP-based real-time detection, OAuth2 auth, DeepSeek Chat API calls with optimized batching, response parsing to extract intents and action recommendations, secure API key storage, input sanitization, error handling and memory cleanup, and a modular design for extensibility. Useful for customer support, sales, and operations teams, it requires Node.js/Node-RED, DeepSeek API keys, and email authentication configured per SETUP.md.
