Case Study: The Honest Company achieves higher trial-to-subscriber conversions and revenue with Retention Science

Improving conversion for The Honest Company

The Honest Company, co‑founded by Jessica Alba, sells nontoxic baby, home, and personal care products with one‑off purchases or subscription bundles. Although free trials drove strong engagement, the brand struggled to convert trial users into paying subscribers: they had rich transactional and behavioral data but lacked the technology to use it effectively for targeted messaging.

Retention Science analyzed that data, created 10 new email templates, and delivered the most relevant, dynamically populated messages to each user at optimal times to build personalized customer journeys. The program drove a 19% increase in email conversion rate, a 7% lift in user conversions, and a 10% increase in revenue per user.
