Do not start from scratch. Use formulas that work.

High-performing formulas:

• Question: "Do you make this [topic] mistake?"
• How-to: "How to [achieve desired result] (without [pain])"
• Number: "7 [things] that [benefit]"
• Urgency: "Last chance: [offer] ends tonight"
• Personal: "[Name], I noticed something..."
• Curiosity gap: "The weird trick that [surprising result]"

Adapt these to your audience and test relentlessly.
