How One Underlined Sentence Increased Response by 327 Percent

In this episode of The Copywriting Podcast, Lucas and Luna dive into a classic direct-mail case study from the 1980s where a single underlined sentence inside a fundraising letter lifted response by an astonishing 327%. They break down the psychology behind why underlining works, how it draws the reader's eye, and when to use it without looking desperate. They also discuss a modern email test from a small e-commerce brand that saw a 68% lift from one underlined word. No fluff, just the specifics of why emphasis works and how to apply it today.
