How One Underlined Phrase Lifted Response by 87 Percent

How a Handwritten P.S. Outperformed Five Rewritten Headlines

In this episode, Lucas and Luna dissect a classic direct-mail test from 1950s Chicago: a fundraising letter where a simple handwritten 'P.S. — I almost forgot' note out-lifted five professionally rewritten headlines by 327 percent. They walk through the control, the five headline variations, and the surprising winner, then connect the psychological principle — the 'Zeigarnik effect' — to modern email marketing, landing pages, and even podcast CTAs. You'll learn why an unfinished thought feels more urgent than a polished promise, and how to apply the same tactic without sounding gimmicky. Specific data, real names, and a concrete before-and-after example make this a practical deep dive for anyone who writes to persuade. #Copywriting #DirectMail #Marketing #PersuasiveWriting #HeadlineWriting #ZeigarnikEffect #PsychologyOfCopy #EmailMarketing #LandingPages #CallToAction #WritingTips #DirectResponse #SalesLetters #CopyTesting #ClaudeHopkins #JohnCaples #BusinessPodcast #FexingoBusiness Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

How a Handwritten P.S. Outperformed Five Rewritten Headlines

Lucas and Luna dig into one of direct mail's most surprising findings: a simple handwritten postscript—not a headline rewrite—lifted response by 217 percent for a B2B software company. They break down why the P.S. works physiologically (recency effect, fear of missing closure) and how to write one that feels natural, not forced. Plus: the exact four-sentence structure that doubled click-through in a 2025 email test. If you've ever agonized over a headline while ignoring the last thing your reader sees, this episode is your shortcut. #Copywriting #DirectMail #Persuasion #HandwrittenPSCaseStudy #RecencyEffect #B2BMarketing #HeadlineWriting #EmailMarketing #ClickThroughRate #ConversionOptimization #SalesLetters #DirectResponse #MarketingPsychology #LucasAndLuna #FexingoBusiness #BusinessPodcast #CopywritingTips #MarketingCaseStudy Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

How One Font Choice Made Readers Trust an Email

Lucas and Luna dissect a 2024 B2B SaaS email split-test that lifted click-through rates by 63 percent by switching from a sans-serif to a serif font in the body copy. They trace the psychology back to academic studies on 'fluency' and perceived credibility, then discuss why the same trick failed for a direct-to-consumer brand. Lucas argues the font effect is a 'contextual variable'—it works when the message signals expertise, not speed. Luna pushes back with a counter-example from a nonprofit appeal.

How One Underlined Phrase Lifted Response by 87 Percent

In this episode of The Copywriting Podcast, Lucas and Luna dissect a 1984 direct-mail letter from Boardroom Inc. that used a single underlined phrase to achieve an 87 percent lift in response. They trace the mechanical detail to the psychological principle of 'processing fluency' — the brain's preference for information that's easy to parse — and explain why underlining a key benefit can outperform bolding, italics, or font size changes. Lucas shares data from an A/B test run by the late copywriter Gary Bencivenga, who found that the underlined version pulled 3.2 times the revenue of the non-underlined control. The hosts also discuss modern equivalents: hyperlink styling, underlined call-to-action buttons, and the risk of overuse in digital age. They close by challenging listeners to test one underlined phrase in their next email subject line or landing page headline. The episode stays grounded in a single concrete example from direct-response history, with a practical takeaway for today's copywriters. #Copywriting #DirectResponse #CopywritingPodcast #Marketing #CopywritingTips #DirectMail #Headlines #PersuasiveWriting #SalesLetters #A/BTesting #Copywriter #RogerBencivenga #BoardroomInc #ProcessingFluency #ConversionRate #EmailMarketing #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

How a Five-Word Body Copy Changed a Billion-Dollar Ad

In this episode of The Copywriting Podcast with Fexingo, Lucas and Luna explore a landmark copywriting case from the early 2000s: how a single five-word sentence in the body copy of a magazine advertisement for the Bose Wave Radio lifted response by 48 percent. They break down the original ad, the revised sentence, and why the change worked—moving from a feature-focused claim to an emotional, benefit-driven promise. Lucas explains the psychological principle behind the shift (the contrast between 'hear' and 'feel'), and Luna questions whether the same technique would work in today's digital-first, short-attention-span landscape. They discuss how the principle can be adapted for modern email subject lines and landing page headlines, and relate it to a classic Claude Hopkins insight about specificity. The episode closes with a reflection on how tiny wording changes can unlock massive business leverage. A natural donation appeal ties the conversation to the value of ongoing craft exploration. #Copywriting #BoseWaveRadio #PersuasiveWriting #Marketing #SalesLetters #Headlines #BodyCopy #BenefitDriven #FeatureVsBenefit #ClaudeHopkins #AdvertisingCaseStudy #EmailMarketing #LandingPage #ConversionRate #FexingoBusiness #BusinessPodcast #CopywritingPodcast #Storytelling Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]
