In general, if a message is purely informational, doesn't ask for action, or is from an unknown source.) Classify it as \"Nothing\".\n\nProvide the Category Only: Respond with the category name and nothing else. Do not add any extra text, explanations, or commentary. Your response should be a single word. and you have 3 categories: \n\n1. Draft\n2. Reply\n3. Nothing\n\nHere is the Email:\n\n{{ $json.text }}",
