When Braintree returns decline code 2016, it means: duplicate transaction. This is classified as a hard decline in the CardData subcategory. This type of decline usually requires direct customer action to resolve.
LostChurn triggers a card update flow, sending a branded email asking the customer to update their payment method. We use Account Updater to automatically refresh card details where available, recovering ~25% without customer action.
Do not retry the same card details. Trigger Account Updater check first, then send a payment update email. Wait 0 hours between outreach attempts. Maximum 0 contact attempts over 14 days before marking as churned.
LostChurn detects 2016 declines in real time and applies the optimal recovery strategy — no manual intervention needed.
