Tips

  • Automatically sets In-Reply-To, References, and threadId headers.
  • Quotes the original message in the reply body.
  • --to adds extra recipients to the To field.
  • Use -a/--attach to add file attachments; it can be specified multiple times.
  • With --html, the quoted block uses Gmail's gmail_quote CSS classes and preserves HTML formatting. Use fragment tags (<p>, <b>, <a>, etc.) — no <html>/<body> wrapper needed.
  • With --html, inline images in the quoted message are preserved via cid: references.
  • Use --draft to save the reply as a draft instead of sending it immediately.
  • For reply-all, use +reply-all instead.
