An inactive customer refers to a person who has previously made purchases or engaged with a business, but has not done so in a significant amount of time. This can be due to a variety of reasons, such as loss of interest, lack of need for the product or service, or dissatisfaction with previous experiences. Inactive customers are often identified as a separate segment in a company’s customer base and efforts are made to re-engage them through targeted marketing strategies. Failure to re-engage inactive customers can result in lost revenue and potential damage to the company’s reputation.
