Case Study: Rainbow Plant Life achieves newsletter growth and a bestselling book launch with Kit

How this vegan food blogger used Kit to launch a New York Times bestselling book and a successful paid newsletter

Rainbow Plant Life, the vegan food brand founded by Nisha Vora, wanted a better way to grow its email list and connect with readers beyond social media. Using Kit, the team replaced a sporadic newsletter experience with a more intentional email strategy that could support recipes, audience growth, and product launches.

Kit helped Rainbow Plant Life build tailored welcome sequences, add opt-in forms to YouTube content, segment subscribers, and send targeted emails for offers like the paid meal plan and cookbook launch. The results were significant: the mailing list grew from 28,000 to over 140,000 subscribers, the paid newsletter reached five figures in monthly revenue and now drives 45% of total revenue, and Kit-powered email helped propel Big Vegan Flavor to #1 on Amazon and later a New York Times bestseller.
