Send a dunning email sequence before subscription cancellation

Set up a four-email sequence triggered the moment a subscription payment fails: an immediate notice, a reminder at day 3 with a direct link to update the card, a warning at day 7 naming the exact cancellation date, and a final notice at day 10. Include the specific decline reason from your payment processor when available.

Why it works: Most failed payments are expired cards, not lost customers, and a clear sequence recovers revenue that would otherwise churn silently.
