5 Dunning Email Templates That Recover Failed Payments (2026)
A dunning email tells a customer their subscription payment failed and asks them to update their card before they lose access. Done well, these emails recover a large share of failed payments, often the difference between keeping a customer and losing them to involuntary churn they never chose. Below are five templates you can adapt, plus the timing and tone that make them work.
Before the templates: the rules that matter
- Send fast, then space out. The first email should go within hours of the failure; open rates are far higher in the first 24 hours than weeks later. Then follow up across the retry window.
- Lead with reassurance, not threat. The customer almost certainly did not mean to lapse. Tell them their account is still active and make the fix a single click.
- Send from your own branded domain. A recognizable sender from your real domain lands in the inbox and gets opened; a generic no-reply address gets filtered.
- One clear call to action. Every email points to the same place: update payment method. No competing links.
Template 1 — First notice (send within hours)
Template 2 — Reminder (day 3)
Template 3 — Card expired (specific cause)
Template 4 — Final notice (end of retry window)
Template 5 — Win-back (after access lapses)
How to know your templates are working
Track recovery rate per email and overall, but measure honestly. Hold back a small random percentage of failed payments from the sequence as a control group, then compare how many recover with emails versus without. The gap is the revenue your templates actually caused, as opposed to customers who would have updated their card anyway. Without that control, any “recovered revenue” figure flatters the emails.
If you sell on Polar, you can skip building and sending all of this by hand. Snagr ships these flows with editable templates, sends them from your own domain, and reports recovered revenue against a built-in holdback.
