How a Solo Dev Used Cold Email to Land 50 Beta Users

In this episode of The Indie Hacker Podcast, Lucas and Luna dive into a practical, often-overlooked growth channel for solo developers: cold email. They break down the story of a solo SaaS builder who landed 50 beta users in one week by sending just 200 personalized emails. Lucas shares the exact strategy — how to find the right prospects, craft a subject line that gets opened, and write a body that converts without sounding spammy. Luna challenges the approach with questions about deliverability, personalization at scale, and whether cold email works for B2C products. They discuss tools like Hunter and Mailshake, the importance of a unique value proposition, and why follow-ups matter more than the first email. If you're a solo developer or indie hacker struggling to get early traction, this episode gives you a repeatable, low-cost playbook to find your first users. #ColdEmail #SaaS #IndieHacker #SoloDeveloper #UserAcquisition #GrowthHacking #BetaLaunch #EmailMarketing #Hunter #Mailshake #Personalization #Outreach #Bootstrapped #Technology #BusinessPodcast #FexingoBusiness #StartupTips #SoloFounder Keep every episode free: buymeacoffee.com/fexingo
