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

Lucas and Luna dig into one of the most controversial copywriting tactics of the past decade: using emojis in email subject lines. They look at a specific case from a mid-sized e-commerce brand that ran a year-long study and saw a 28 percent lift in open rates when using a single emoji in the subject line. But they also unpack the risks — which emojis work, which backfire, and how audience demogra...

Two versions of the same testimonial. One written by a professional copywriter at the ad agency. The other scribbled on a napkin by the actual customer. Version A came first.

Lucas and Luna unpack why the customer's own words, with all their awk...
