# langmail

> Email preprocessing for LLM consumption. Parse, clean, and structure raw RFC 5322 emails into Markdown optimized for language models. Written in Rust, available for Node.js, Python, and Rust.

langmail converts raw emails into clean, structured formats for LLM pipelines. It handles HTML-to-Markdown conversion, reply chain detection, signature stripping, and CTA extraction. Two main functions: `preprocess()` for parsing and `toLLMContext()` for LLM-ready output.
