Chenell and Dylan break down everything that happened with the second annual 30 Days of Growth — 30 cross-promotions with 30 different newsletter creators, published as a daily email series over 30 consecutive days. They cover what worked, what flopped, why Chenell wishes she'd done opt-ins instead of opt-outs, how 2,086 new subscribers came in (beating last year's 1,757), and which tips from the series they found most compelling — from AI-powered subject line analysis to a 5x landing page conversion boost from changing one button.
