One and done

Customer retention is critical for the long-term growth of your brand. It is not enough to acquire a customer who makes a single purchase. It is essential to find ways to convince your one-time buyers to become long-term, repeat customers.

Use a list of one-time buyers to identify combinations of products, time windows, and lookalike audiences that can be used as the starting point for campaigns that focus on turning one-time buyers into repeat customers.

The following sections describe using the the Segment Editor to build a segment that returns a list of customers who have purchased only one time.
