The client had more than eleven years of sales history and a large customer base that nobody had ever really read.
We measured return cycles by age group and by store, found the months in which customers came back and those in which they drifted away, and isolated those who had left during the covid years and never returned. Then we called back the lost customers and those in their return window, tracking every reactivation.
In the first year the return on investment was 1046%, measured only on lost customers who came back, without acquiring a single new customer.
