    In episode 73 of The Copywriting Podcast, Lucas and Luna dive into a fascinating direct mail test from the 1980s where a simple handwritten margin note added to a typed sales letter doubled the response rate. They explore the psychology behind why a personal scribble in the margins outperformed polished copy, the specific words that worked best, and how this principle translates to modern email and landing page copy. Learn why imperfection signals authenticity and how to apply the 'margin note effect' without looking gimmicky. Plus, a surprising twist: a test where the same note in red ink flopped. Full of actionable takeaways for anyone writing persuasive copy today.

  • How a Single Typo in a Headline Boosted Response by 31 Percent

    In this episode of The Copywriting Podcast, Lucas and Luna explore the surprising power of intentional imperfection in copywriting. They dissect a famous direct-mail test where a deliberately misspelled word in a headline lifted response rates by 31 percent — and why that worked. They discuss the psychology of processing fluency, the role of perceived authenticity, and when a 'flaw' can make copy feel more human and trustworthy. The episode includes specific examples from a 1990s fundraising appeal, a modern SaaS landing page test, and actionable takeaways for writers willing to leave a typo in. Plus: how one comma changed the meaning of a $14 million offer.

  • How a Handwritten Margin Note on a Typed Letter Doubled Response

    In episode 70 of The Copywriting Podcast with Fexingo, Lucas and Luna dive into a surprising direct mail A/B test from 2023. A financial newsletter company tested a four-page typed sales letter against a version with a single handwritten margin note in the bottom right corner: 'Luna — this is the part you need to see.' The handwritten version outperformed by 107%, with a 2.1% response rate versus 1.0%. Lucas walks through the psychological mechanics — social proof, personalization, scarcity of handwriting in a typed world. Luna pushes back on whether the effect holds in email, and they discuss a 2025 study from the Journal of Consumer Psychology that measured increased neural activity in the prefrontal cortex when participants saw handwritten elements. They touch on the cost of handwriting at scale, the 'ink authenticity factor,' and how to test this without breaking the bank. Practical takeaway: start with a handwritten PS on your next control letter.

  • How a Story in a Sales Letter Outperformed a List of Features

    In this episode, Lucas and Luna break down the exact moment a narrative-driven sales letter generated 62% more revenue than a feature-focused control — using the real-world case of a B2B software company that tested two versions of its landing page. They walk through the structural choices that made the story work: the specific customer persona arc, the moment of tension that held readers, and the single sentence that lifted conversion by 19 percentage points. No vague theory — just the copywriting mechanics behind a concrete A/B test. If you've ever wondered when to tell a story versus when to bullet-list benefits, this episode gives you a usable framework. Hosts Lucas and Luna also briefly touch on how listener support through buy me a coffee dot com slash fexingo keeps the podcast ad-free and focused on practical marketing experiments.

  • How an Uncomfortable Pause Changed a Sales Letter Response Rate

    In this episode of The Copywriting Podcast, Lucas and Luna examine a specific sales letter test from a mid-2000s fundraising campaign where a single, uncomfortable pause in the copy—a strategically placed ellipsis and line break—lifted response by 39 percent. They break down why silence in the middle of a sentence actually increased readership, how the pause mirrored the reader's own hesitation, and why modern digital copy can still benefit from this counterintuitive technique. The discussion includes the original letter's subject (a children's hospital appeal), the control vs. treatment data, and a principle borrowed from jazz: the notes you don't play matter as much as the ones you do. Luna pushes back on whether the effect is replicable in skimmable web copy, and Lucas shares a specific application for email subject lines. This is the kind of granular detail that separates good copy from breakthrough copy.

  • How a One-Sentence Handwritten PS Lifted Response by 41 Percent

    In this episode, Lucas and Luna break down the surprising power of the handwritten postscript in direct mail and email. They examine a classic test from a nonprofit fundraising letter: a typed one-page appeal with a typed PS versus the same letter with a brief, handwritten PS added. The handwritten version outperformed by 41 percent. They discuss why a PS works—as a recency effect, a personal nudge, and a permission to skim—and how that principle extends to digital marketing today. Specific examples from a 2025 email campaign show a 22 percent lift in click-throughs when a simple, handwritten-style PS was included. The hosts also explore the psychology of perceived effort: a handwritten note signals that the sender cared enough to write an extra line, building trust and urgency. No vague theory—just a concrete tactic listeners can test in their next campaign.

  • How a 2-Word Headline Outperformed a 10-Word One

    Lucas and Luna dissect a classic A/B test from a 2023 B2B campaign where a two-word headline — 'Revenue Velocity' — generated 58% more clicks than a ten-word alternative. They trace the psychology behind ultra-short headlines, unpack the copywriting principle of 'semantic density,' and explain why brevity often beats completeness in attention-scarce environments. The episode draws on data from a real SaaS landing page test and ties it to historical examples from Claude Hopkins and David Ogilvy. Listeners walk away with a concrete framework for testing short vs. long headlines in their own copy.

  • How One Testimonial Beat a Professional Endorsement

    In episode 65 of The Copywriting Podcast, Lucas and Luna unpack a classic direct-mail test from the 1990s: a plain customer testimonial outperformed a glossy celebrity endorsement by 44 percent. They explore why social proof from an 'average Joe' often trumps expert authority in persuasive writing, how the principle applies to modern email campaigns and landing pages, and a specific lesson for today's marketers about matching proof to the reader's identity. The episode includes practical takeaways for B2B and B2C copywriters, plus a quick look at how HubSpot and Mailchimp have used customer stories in their own marketing. No fluff, just one concrete case you can use Monday morning.

  • How a Commas Worth of Pause Boosted Readership by 29 Percent

    Episode 64 of The Copywriting Podcast with Fexingo digs into the overlooked power of punctuation — specifically, how adding a single comma in the right place lifted readership by 29 percent in a controlled split-run test. Lucas walks through the 1972 direct-mail experiment by copywriter John Caples, where two versions of a subscription letter for 'The Wall Street Journal' differed by only a comma before the word 'too' in the lead paragraph. Luna compares it to modern email open-rate tests, and they unpack why a forced pause creates micro-commitment in the reader's brain. The episode includes practical rules for comma placement in sales copy and a warning against over-punctuation. No fluff — just one precise, replicable technique that any marketer can test today.

About The Copywriting Podcast with Fexingo: Sales Letters, Headlines, and Persuasive Writing

From the publisher's feed

Lucas and Luna sit at a writer's desk, a vintage typewriter between them, and argue about the first line of a sales letter. They don't debate 'write better' platitudes. They pull up real campaigns: the 1985 Boardroom bulletins that ran for a decade, the long-form VSL that sold a $2,000 course with a 42% conversion rate, the direct-mail package that lifted response 18% by changing one headline word. Lucas, in his tweed blazer, traces the rhythm of a sentence aloud; Luna, in her burgundy cardigan, crosses out every adjective that doesn't carry weight. Together, they show you what separates a persuasive read from a scroll-past. Each episode picks one letter, one headline, one bridge paragraph, and dissects it line by line—why it works, what it assumes about the reader, where it could break. The listener is someone who writes for a living: copywriters, marketers, founders writing their own landing pages, anyone who has stared at a blinking cursor and needed a better opening. No fluff, no 'write like this' formulas. Just the craft of selling with words, examined by two people who respect the reader's attention. After listening, you'll see every email subject line and ad headline differently—and you'll know what to change.
