Why Subject Line Personalization Can Backfire

Lucas and Luna explore a surprising email marketing pitfall: over-personalized subject lines that actually reduce open rates. Drawing on a 2025 study by the Email Experience Council, they break down why using a subscriber's first name or recent purchase data can feel invasive or gimmicky—especially for B2B audiences. They walk through real examples from a SaaS company that saw open rates drop 12% after adding personalized fields, and share smarter ways to use subscriber data. The episode covers when personalization works (abandoned cart triggers, welcome flows) versus when it hurts (cold outreach, weekly newsletters), and ends with a framework for testing relevance vs. creepiness. #EmailMarketing #SubjectLinePersonalization #OpenRates #Marketing #EmailExperienceCouncil #B2BEmail #SaaSMarketing #PersonalizationBacklash #SubscriberTrust #EmailNewsletters #FexingoBusiness #BusinessPodcast #MarketingPodcast #EmailDeliverability #DataPrivacy #ABTesting #Segmentation #CustomerExperience Keep every episode free: buymeacoffee.com/fexingo
