Episode 125 of The Email Marketing Podcast with Fexingo digs into the power of A-B testing to reduce subscriber churn. Lucas and Luna explore a real case: an outdoor gear retailer that tested two versions of their weekly newsletter—one with product-heavy content, one with storytelling and user-generated photos. The winner cut unsubscribes by 30% over three months. They break down the test setup, sample size, metrics, and why most marketers test the wrong things. Plus, a practical framework for running tests that actually move retention. No fluff, just actionable email science.
