ChatGPT and Claude open with your prompt already typed in. Gemini can't be filled in from a link, so its button copies your prompt: paste it into the new chat.
The prompt that gets copied
Below are my last 30 email subject lines with their open rates. Compare the top 10 with the bottom 10 and tell me what the winners have in common: length, wording, curiosity, numbers, personal tone or anything else you see. Turn that into a simple 5-point scoring guide based only on my data. My next email is about [EMAIL TOPIC, e.g. why I stopped offering discounts]. Write 8 subject lines, score each one with the guide and recommend the top two, each with a matching preview text line. Tell me if my sample is too small or too mixed to trust. Subject lines and open rates: [PASTE SUBJECT LINES]
Paste your last 30 subject lines with their open rates and AI builds a scoring guide from your winners, then scores and rewrites the subject line for your next email.

- Paste them into the prompt with your next email's topic.
- Pick a subject line and A/B test it if your email tool allows.
