## Resource

In this episode of The Newsletter Podcast, Lucas and Luna dive into the mechanics of A-B testing for email newsletters, exploring how creators use subject line tests, content variations, and send-time experiments to boost engagement. They break down a real-world case: a Substack writer who doubled click-through rates by testing two subject line styles over 30 days. The hosts discuss statistical significance, sample sizes, and common pitfalls, offering practical tips for newsletter operators of all sizes. Listeners learn why 'winner takes all' thinking is dangerous, how to set up tests in Beehiiv and Substack, and when to trust your gut over the data. #ABTesting #NewsletterMarketing #EmailMarketing #Substack #Beehiiv #ClickThroughRate #SubjectLines #Optimization #DataDriven #MarketingTips #ContentStrategy #GrowthHacking #Engagement #ConversionRate #Business #Marketing #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
