How a Handwritten P.S. Beat the Entire Body of a Sales Letter

In this episode of The Copywriting Podcast, Lucas and Luna examine the remarkable 1968 direct mail experiment by copywriting legend John Caples, where a simple handwritten postscript in blue ink generated 57% more sales than the full two-page letter alone. They break down the psychology behind why the P.S. works—recency effect, intimacy, and fear of missing the call to action—and share modern equivalents like email preview text and Amazon's 'Customers who bought this also bought' algorithm. The hosts also explore how Swiss copywriter Dieter Rams applied similar minimalist principles to product design, proving that the most persuasive detail is often the one that feels least like a sales pitch. Tune in to discover why the best copywriters save their strongest argument for last. #JohnCaples #DirectMail #Copywriting #Persuasion #Marketing #SalesLetters #PS #RecencyEffect #CallToAction #Minimalism #DieterRams #Psychology #Headlines #Advertising #Business #FexingoBusiness #BusinessPodcast #CopywritingPodcast Keep every episode free: buymeacoffee.com/fexingo
