Mailmerge-JS

Mailmerge-JS is an open-source, AI-powered command-line tool that allows users to draft and send highly personalized templated emails directly from their Gmail inbox. It leverages OpenAI and the Gmail API to automate the email drafting process, letting users write templates in HTML, Markdown, Text, or Jinja formats with loosely defined variables in pseudocode using double curly braces. The AI synthesizes the final email content against any data file provided, handling missing or incomplete data gracefully. Users bring their own API keys and credentials, ensuring full data privacy with no data stored server-side.
