“There's an old copywriting maxim: sell the smile, not the fluoride. Nobody buys toothpaste because of fluoride — they buy it for the smile. Your paywall copy should be about the life outcome, not the feature list.”

Sell the smile, not the fluoride: outcome-and-emotion copy outperforms feature copy on paywalls

Moore applied this to fitness apps: instead of '500 workouts' or 'AI-generated plans,' the winning copy described feeling confident, having more energy, and hitting goals. Stone confirmed the same pattern at Citizen: users don't want a 'real-time crime alert' feature — they want to feel safe. Outcome-and-emotion copy resonates because the user's self-image is more motivating than a technical capability.
