Copyhackers

Joanna Wiebe coined the term "conversion copywriting" and built Copyhackers around the craft of writing words that actually get people to click, buy, or sign up, treating copywriting as a testable discipline rather than an art. The newsletter shares specific before-and-after examples and the reasoning behind why one version of a headline or button outperforms another.

It's genuinely useful for anyone who writes landing pages, emails, or ads for a living, less about brand voice and more about the specific words that move a reader from hesitation to action. Marketers and founders who write their own copy get practical, immediately testable advice here.
