Latest / The Copywriting Podcast with Fexingo: Sales Letters, Headlines, and Persuasive Writing / How a Single Typo Boosted Response by 27 Percent
Transcript
- Lucas: So we have talked a lot about the power of specific words, underlines, even punctuation. But today I want to talk about something most copywriters are taught to avoid at all costs: typos. Luna: Typos? Aren't they the enemy of credibility? Lucas: Exactly what I would have said. But there is a fascinating case from the folks at Marketing Experiments where a headline with a simple typo actually outperformed the correct version by 27 percent. And it wasn't a fluke — the psychology behind it is really interesting. By the way, if these marketing conversations have sparked something you have actually used, and you appreciate that we keep this podcast completely ad-free, listener support is what makes that possible.

Lucas: It was a headline for a weight loss program. The control headline was 'Lose Weight Fast!' and the variation had a typo: 'Lose Weigt Fast!' — missing the letter 'h' in weight. The typo version got 27 percent more clicks. Luna: That is counterintuitive. Why would a mistake make people more likely to click? Lucas: The theory is that the typo made the ad feel less polished, more human. People subconsciously perceive imperfections as signs of honesty. If an ad looks too slick, it can feel manipulative. A small flaw signals that it wasn't written by a corporate machine. Luna: So it is about authenticity. I have seen similar results in email subject lines — one campaign I ran, a subject line with a missing space actually had higher open rates. Lucas: Exactly. There is a concept called the 'pratfall effect' — when a competent person makes a small mistake, it actually makes them more likable. The same principle applies to copy. But it only works if the typo is subtle and the reader doesn't think you just don't care. Luna: Right. If the typo is too obvious or looks like sloppy work, it backfires. So where does the sweet spot lie? Lucas: The sweet spot is a typo that is noticeable but not jarring. It should be a common misspelling — like 'recieve' instead of 'receive' — or a missing letter that doesn't change the word's sound much. The reader might even think they misread it and then subconsciously decide it's more trustworthy. Luna: That is fascinating. So are there specific places where a typo is more effective? Headlines, subject lines, body copy? Lucas: Headlines and subject lines are the best candidates because they are short and the typo is more likely to be noticed. In longer body copy, a typo can just look like a mistake. One study by a direct mail company found that a typo in the headline increased response by 17 percent, but a typo in the body copy decreased it by 6 percent. Luna: So context matters. And I imagine the product category matters too — a typo for a luxury brand might hurt trust. Lucas: Absolutely. For a high-end watch brand, any typo is a sign of poor craftsmanship. But for a quirky start-up or a weight loss program that positions itself as the 'real' option, a small imperfection can reinforce the message. Luna: Have you tested this yourself? Or seen any other notable examples? Lucas: I have run a few tests with email subject lines. One test for an online retailer used 'Flash Sale Today' versus 'Flash Sale Toady' — and the typo version had a 12 percent higher open rate. But I also had a test where the typo was too obvious — 'Get Your Free Gifit' — and it bombed. Luna: So the rule of thumb is: one subtle, plausible mistake per piece. And it should feel accidental, not intentional. Lucas: Exactly. The reader should think 'Oh, someone made a typo, but the offer is still good' rather than 'This is clearly a stunt'. There is also a timing element — if you run a split test with a typo, run it for a shorter period because the novelty wears off. Luna: Good point. I want to ask about the ethics of intentional typos. Is it manipulative? Lucas: That is a fair question. I think it is no more manipulative than using emotional language or urgency. The key is that the product or offer must deliver on its promise. If you use a typo to get clicks but the content is junk, you are exploiting trust. If the offer is solid, a typo is just a stylistic choice that can improve the reader's experience. Luna: So the typo is not the magic — the authenticity it signals is. You still need a strong headline and a compelling offer. Lucas: Exactly. The typo is just one lever. And it doesn't work for every audience. B2B buyers, for instance, expect precision. A typo in a whitepaper headline would probably hurt credibility. But for B2C or DTC brands aiming for a conversational tone, it can be a useful tool. Luna: I am reminded of the famous 'They Laughed When I Sat Down at the Piano' ad — that had a very conversational, slightly imperfect tone. No typo, but the same principle of breaking perfect form. Lucas: Great example. That ad uses colloquial language and a story, which also signals authenticity. The typo is just a faster way to trigger that same feeling. But you have to be careful: if your entire brand voice is polished and formal, a sudden typo will confuse readers. Luna: So consistency matters. If you are going to use typos, your brand should already have a conversational or rebellious tone. Lucas: Right. And the best way to find out is to test it yourself. Run an A/B test on a headline or subject line with one small typo against the correct version. Make sure the sample size is large enough to be statistically significant. Luna: What about using typos in social media posts? I have seen accounts that intentionally misspell words to seem 'relatable'. Lucas: That can work, but it is a different dynamic. Social media users expect more informal language. A typo can make a brand seem more human, like you are just a person posting. But overusing it can look like you don't care about quality. The sweet spot is using it sparingly for emphasis. Luna: So it is a subtle art. I think the key takeaway for me is that perfection is not always persuasive. Sometimes a little flaw can build a better connection. Lucas: That sums it up well. The copywriting rulebook says 'check your spelling' — and you should, most of the time. But if you want to experiment, a single, intentional typo might just give you a surprising lift. Just don't tell your English teacher. Luna: Ha! Our secret is safe. For now, I am going to think about where I might try this in our next campaign. Lucas: Let us know how it goes. And if listeners try it, we would love to hear your results too.
