Case Study: Rocksbox boosts email deliverability and engagement with Kickbox

How Rocksbox used the Kickbox's real-time verification API to transform the way people discover and buy jewelry, achieving a high inbox placement and sender reputation

RocksBox, a jewelry membership retailer, needed a way to keep email data accurate and high-quality as its marketing database grew and its engagement strategy expanded. The company wanted to maintain strong inbox placement, improve customer engagement, and reduce issues tied to invalid email addresses. Kickbox helped RocksBox address these challenges with its email verification product, including the real-time API.

By integrating the Kickbox API into its signup forms, RocksBox verified email addresses at the point of capture and tagged them based on quality. With Kickbox, RocksBox achieved a 27% decrease in hard bounce rate, a 50% decrease in account login issue inquiries, a 10% improvement in welcome-series open rates, and a 42% increase in click-through rate. The company also saw average month-over-month improvements of 25–30%, helping drive about 30% of total purchase revenue each month.
