Twice Goal

The Goal

Ramp Up New Customer Acquisition

Twice is a sophisticated online marketer. After years of running extensive user acquisition campaigns, they've developed clear KPIs, goals and attribution methods. They came to Rockerbox hoping to find a new vendor that can bring added scale while leveraging their historical learnings.


The Rockerbox Solution

Recency Marketing Meets Subscription Customers

Twice had a very unique set of users. As Twice helps customers acquire brand name clothing, its critical for Rockerbox to seperate potential customers that are interested in just high end clothing from those that are open to buying it secondhand. By analyzing the different behaviors that drove Twice's existing customers to visit, Rockerbox was able to figure out distinguishing patterns and optimize our campaigns accordingly.

The Results

Recency Prospecting Delivers New Customers at Lower CPAs

Once Rockerbox was able to distinguish between shopper types (those that are open to secondhand clothing versus those that aren't), Rockerbox's technology was able to target and optimize Twice's prospecting campaign. Over the course of 3 months, Rockerbox was able to decrease CPAs by 57% while almost doubling post click conversions.

We have been very impressed with Rockerbox's performance, technology and service. Glad that we chose to work with them.
