Dunning

Dunning is one of the oldest concepts in accounts receivable, dating back centuries to when creditors would send formal notices demanding repayment. In the modern subscription economy, dunning has evolved into an automated, multi-channel communication strategy designed to recover failed payments while preserving the customer relationship.

A dunning campaign usually follows a predefined sequence. When a payment fails, the system sends an initial notification informing the customer and prompting them to update their payment method. If the payment remains unresolved, follow-up messages are sent at intervals — often escalating in urgency. The final message typically warns that the subscription will be canceled if payment is not collected within a grace period.

Effective dunning strikes a balance between urgency and empathy. Overly aggressive messaging can alienate customers who may have experienced a temporary issue like an expired card or insufficient funds. On the other hand, passive or infrequent follow-ups can result in lost revenue that could have been recovered with timely action.

Modern dunning systems go beyond simple email reminders. They combine intelligent retry logic (automatically re-attempting the charge at optimal times) with personalized communication tailored to the reason for the failure. For example, a customer whose card was declined due to insufficient funds might receive a different message than one whose card expired.

LostChurn automates the entire dunning workflow, using AI to personalize messaging, optimize send times, and coordinate retries with communication touchpoints to maximize recovery rates while minimizing customer friction.
