Prompt objective
Create subject lines that consistently exceed 25% open rate for online store email marketing campaigns.
Real use case
The women's fashion e-commerce StyleBox has an email list of 45,000 contacts but an average open rate of 12%. Subject lines are generic ('Weekly New Arrivals', 'Check Out Our Deals'). They need to at least double opens to justify email marketing investment.

Replace the placeholders with your own context before you run the prompt. That usually improves the first output more than adding more instructions later.
