💡 Tips for Best Results

• Quantify Your Benefit: In the KEY_BENEFIT field, use numbers and data whenever possible. 'Increase lead conversion by 30%' is far more compelling than 'get more leads.'
• Hyper-Specific Audience: Be precise with your TARGET_AUDIENCE. 'HR Managers at tech companies with 50-200 employees' will yield better results than just 'HR Managers.'
• Test Different Tones: A 'Curious' tone (e.g., 'a question about...') might work for one campaign, while a 'Direct' benefit-driven tone (e.g., 'save 10 hours/week') works for another. Test to see what your audience responds to.
• Personalize When Possible: The generated subjects are great templates. For even better results, add personalization tokens like `[First Name]` or `[Company Name]` before sending.
