The cost involved in keeping the existing customers engaged with the brand or business is broadly referred to as Customer Retention Cost. It encompasses a range of activities like customer support, loyalty programs, re-engagement campaigns, remarketing, personalized discounts, and other promotional initiatives targeted at the existing customer base.
