Case Study: BOOM! by Cindy Joseph achieves 26X ROI on win-back mail with PostPilot

Ezra Firestone's BOOM! Achieved a 2600% ROI with Postcards

BOOM! by Cindy Joseph, the beauty brand founded by ecommerce veteran Ezra Firestone, needed a better way to improve retention and customer lifetime value. Like many cosmetics brands, BOOM! faced high acquisition costs and the “one-time buyer” problem, making repeat purchases critical to profitability. The company turned to PostPilot’s Shopify direct mail solution to help re-engage customers before they churned.

Using PostPilot, BOOM! launched a simple automated win-back postcard campaign targeting customers who had purchased before but hadn’t bought again in 1–2 months. The campaign took just minutes to set up and ran automatically, sending a 15% off limited-time offer to defecting customers. Within the 45-day tracking window, PostPilot helped turn $1,510 in spend into $39,732 in sales, producing a 2,631% ROI.
