Case Study: Rocketbook achieves data-driven engagement and stronger customer relationships with Klaviyo

How Rocketbook uses Klaviyo to strengthen customer relationships with targeted, data-backed emails

Rocketbook, the Boston startup that makes reusable, app-connected notebooks, was sitting on a goldmine of customer data but couldn’t fully act on it. After growing beyond basic Mailchimp sends, the team needed a more powerful, flexible email platform to turn app engagement and customer signals into personalized, long-term relationships and smarter marketing.

They moved to Klaviyo, brought in a Klaviyo specialist and hired a dedicated marketer to build persona-driven, triggered campaigns (based on five key personas and in-app behavior), automate NPS feedback, and feed insights back into product development. The result: email-attributed revenue doubled from Q2 to Q3, educators’ targeted emails saw a 130% lift in CTR, the educator persona list grew 10x, and more than half of active subscribers have self-identified — all driving higher engagement, retention, and product improvements.
