How many times should a payment be retried in a dunning sequence?

Best practice is 3–5 retries spaced 2–5 days apart, with different retry timing (some payment failures recover better at end of month or beginning of month when account balances reset). The optimal sequence depends on the customer base and card network patterns.

What communication channel works best for dunning outreach?

Email combined with SMS achieves higher recovery rates than either alone. Chat-based AI outreach — reaching a customer who is on the site — has the highest recovery rate because the customer can update payment immediately in the moment of contact.

What happens to a subscriber's account during the dunning window?

Most merchants continue service during the retry window to avoid service interruption as a reason for the customer not to bother updating. The subscription is suspended only if all retries fail and the dunning window expires without payment recovery.

Glossary

Dunning

Dunning is the automated process of recovering failed subscription payments through a scheduled sequence of payment retries and customer communications designed to update payment information and prevent involuntary churn.

What it means

Key insight

Most involuntary subscription churn is recoverable — an AI-driven dunning sequence that reaches customers quickly and makes updating payment easy captures the majority of it.

When a subscription payment fails — due to an expired card, a declined charge, or a lost card — the merchant faces a choice: let the subscription lapse or pursue recovery. Dunning is the recovery process: a structured sequence of automated payment retries (typically 3–5 attempts over 1–2 weeks) paired with customer outreach (email, SMS, or chat) prompting the customer to update their payment information. The customer communications in dunning are support interactions: the customer needs to understand why they received the message, how to fix the payment issue, and what will happen to their subscription if they don't. An AI support agent that handles dunning-related customer responses — answering questions about the failed charge, providing a direct link to update payment, and confirming when a retry will occur — significantly improves recovery rates over passive automated emails.

Why it matters

Involuntary churn — subscribers who leave not because they want to but because their payment failed — is a substantial and recoverable revenue loss for subscription businesses. Industry estimates suggest 20–40% of subscription churn is involuntary. Dunning processes that include AI-supported customer communication recover meaningfully more revenue than those relying on static email sequences, because customers who receive a quick, helpful answer to their payment question act on it — while customers who receive a generic email often don't.
