Harry Dry

Harry Dry does not write about marketing. He shows you marketing. Every piece of content he creates starts with a real example — a cold email that generated $100M in revenue, a typo domain that drives 10% of a company's ARR, a CTA rewrite that doubled conversions — and works backwards to the principle. The example is always the headline. The lesson is always the ending. Everything in between is him connecting the two as efficiently as possible.

His newsletter subject lines are worth studying as a masterclass in their own right. He never uses abstract concepts as openers — 'How to write better CTAs' is not a Harry Dry subject line. Instead he writes 'Three ways to add warmth to your CTA' or 'How Basecamp makes $99/month feel cheap'. Every subject line contains a specific action, a specific company, or a specific number. The reader always knows exactly what they're getting — and it always sounds more interesting than a generic alternative would. Specificity is his default mode and his primary creative constraint.

If you want to write like Harry Dry, start with the example rather than the lesson. Find a real piece of copy, a real campaign, or a real result that surprised you, and ask: what principle does this prove? Write that example into the headline. Explain the principle in the body. His writing teaches that the most persuasive marketing content is not advice — it is evidence. Advice tells people what to do. Evidence shows them it already works.
