5 Dunning Letter Templates to Copy in 2026
A dunning letter is the email you send a customer after their subscription payment fails, asking them to update their card so billing can continue. Below are five complete dunning letter templates you can copy today: a day-0 soft notice, a day-3 reminder, a day-7 urgency email, a day-14 final notice, and a post-cancellation win-back.
Failed payments quietly cancel more subscriptions than unhappy customers do, and most of them are fixable: a card expired, a bank flagged a recurring charge, a limit reset overnight. This post is the practical half of dunning. For the background on how the whole system works, read our guide to dunning management (https://subzwallet.com/blog/what-is-dunning-management).
The five-email dunning sequence at a glance
Each dunning letter template below maps to one stage of a failed payment. Timing matters as much as copy, so send them in this order and pair each one with a card retry. More on the schedule further down.
- Day 0, soft notice: assume good faith and tell the customer the retry is automatic.
- Day 3, reminder: ask directly for a card update and lead with the link.
- Day 7, urgency: name the exact pause date and what they lose.
- Day 14, final notice: a real deadline, 48 hours out, with a one-minute fix.
- After cancellation, win-back: make restarting one click, since these customers never chose to leave.
Five dunning letter templates you can copy today
Replace the bracketed placeholders, adjust the sign-off to your brand voice, and these are ready to send. Every good failed payment email has one job: get the customer to the update-payment link with as little friction as possible.
1. Day 0: the soft notice
Send this within an hour of the first failed charge. The tone stays relaxed on purpose: most first failures are temporary, and your first automatic retry may clear on its own. You are informing, not chasing, so keep any mention of cancellation out of it.
Subject: A quick heads-up about your [Store name] subscription
Hi [First name],
We tried to process the payment for your [Product] subscription today and it didn't go through. This happens all the time: cards expire, banks get cautious about recurring charges, daily limits reset overnight.
Nothing is required from you yet. We'll retry the charge automatically in a few days. If you've recently received a new card, though, you can update your details in about 30 seconds here: [Update payment link]
Your subscription is still active and your delivery schedule hasn't changed.
Thanks for being with us,
The [Store name] team
2. Day 3: the reminder
Send this the same day your second retry fails, usually day 3. Two failures in a row mean the card on file is probably dead, so drop the no-action-needed framing and ask plainly for the update. Lead with the link.
Subject: Your [Product] subscription is on hold
Hi [First name],
We've now tried your card twice for your [Product] subscription and neither charge went through, so your next order is on hold.
Updating your payment method takes under a minute: [Update payment link]
The usual culprits are an expired card, a replacement card from your bank, or a fraud flag on subscription charges. If your bank is declining the charge, a quick call to them usually clears it.
As soon as a payment succeeds, your order ships on the normal schedule.

3. Day 7: the urgency email
Send this at the one-week mark, right after the third retry fails. This is your first dunning email with real urgency, so name the exact pause date and spell out what the customer loses. Also open the door to alternatives, because some failed payments are really customers who wanted to skip a month.
Subject: Action needed: your [Store name] subscription pauses on [Date]
Hi [First name],
We still haven't been able to charge the card on file for your [Product] subscription. If it isn't updated by [Date], your subscription will pause and your upcoming delivery will be cancelled.
The fix takes about a minute: [Update payment link]
Pausing also means losing your subscriber price, and you'll stop earning rewards on these orders while it lasts.
If something else is going on, maybe you'd rather skip a month, change your delivery date, or switch products, just reply to this email and we'll sort it out. We'd rather adjust your plan than lose you over a card number.

4. Day 14: the final notice
Send this 48 hours before you actually cancel, around day 12 to 14. The subject line should say exactly what happens and when. Vague final notices get ignored, and customers who are then surprised by a cancellation blame you, not their bank.
Subject: Final notice: your subscription cancels on [Date]
Hi [First name],
This is our last reminder. We haven't been able to charge your card for [Product] since [First failure date], and your subscription will be cancelled on [Date] unless your payment method is updated before then.
Update your card here: [Update payment link]
If the subscription cancels, your scheduled deliveries stop and your current subscriber price is no longer guaranteed if you restart later.
If you meant to cancel, no hard feelings, and there's nothing you need to do. If not, that link takes about a minute.
[Store name]
5. After cancellation: the win-back
Send this 3 to 7 days after the contract cancels. Customers lost to failed payments never decided to leave, which makes them the warmest win-back audience you have. Keep their plan on file, make reactivation one click, and consider a small incentive if your margins allow one.
Subject: We saved your spot, [First name]
Hi [First name],
Your [Product] subscription was cancelled last week because we couldn't process a payment. Since you never actually asked to leave, we've kept your plan, your preferences, and your delivery schedule exactly as they were.
Restart in one click here: [Reactivation link]
Add a current card and your next delivery goes out on the usual schedule. Want a different frequency or product this time? You can change both on the same page.
We'd love to have you back.

How should you time dunning emails with card retries?
A dunning email works best when it lands right after a failed retry, not on an arbitrary calendar day. Email a customer while the next automatic retry might still succeed, and you're asking them to do work the system may do by itself. Retry without emailing, and you burn attempts on a dead card. Here is a schedule that works for most subscription stores:
- Day 0: the charge fails. Send the soft notice within the hour and schedule the first retry for day 3. Many soft declines, like insufficient funds or daily limits, clear on their own within a couple of days.
- Day 3: retry the card. If it fails again, send the reminder the same day.
- Day 7: retry again. On failure, send the urgency email with a concrete pause date.
- Day 12: run the final retry. If it fails, send the final notice and set cancellation for day 14.
- Day 14: cancel the contract if the card still fails, then send the win-back 3 to 7 days later.
Two cautions. Keep total retries to four or five, because hammering a dead card looks like fraud to the issuing bank and can hurt your future authorization rates. And stop the sequence the instant a payment succeeds; nothing torches goodwill like a final notice sent to someone who already paid. Getting this loop right is one of the fastest ways to reduce subscription churn (https://subzwallet.com/blog/reduce-shopify-subscription-churn).
Four rules for editing these templates
- Blame the card, not the customer. Your card didn't go through reads very differently from you failed to pay. Most failures are involuntary, so your tone should assume good faith until day 14.
- One action per email. Every message gets exactly one link: update your payment method. Extra links and offers dilute the click you actually need.
- Plain subject lines win. Action needed: your subscription pauses Friday outperforms anything clever, because clarity is what gets a busy person to open a billing email.
- Send from a monitored address. Customers reply to dunning emails asking to skip a month or swap products. If those replies hit a no-reply void, you lose saves you had already earned.
Let subZwallet send this sequence automatically
You can run these five letters by hand from your email tool today, and if payments are failing right now, you should. But manual dunning gets fragile fast: every send has to line up with a retry, stop the moment a customer pays, and recalculate its dates for each customer separately.
subZwallet is a Shopify subscription app (https://subzwallet.com/shopify-subscription-app) with smart dunning built in. It retries failed cards on an automatic schedule, sends customizable recovery emails after each failed attempt, and halts the sequence the instant a charge succeeds. Your customers land in a self-service portal where they can update their payment method, or pause, skip, and swap on their own, which quietly resolves the can-I-just-skip-a-month replies before they happen.
Plans start free for up to 50 subscriptions, with paid plans from $99 per month and a 14-day trial (https://subzwallet.com/pricing). Install it from the Shopify App Store (https://apps.shopify.com/aubzwallet), put your brand voice into the recovery emails, and your dunning runs itself from the next failed charge onward.
Frequently asked questions
What is a dunning letter?
A dunning letter is a payment reminder sent to a customer whose charge failed or whose invoice is overdue. In subscription commerce it is almost always an email asking the customer to update their card so billing can resume. The name comes from an old English word meaning to press for payment.
How many dunning emails should I send?
Four before cancellation is the standard: a soft notice on day 0, a reminder around day 3, an urgency email at day 7, and a final notice near day 14, each sent after a card retry fails. Add one win-back email after cancellation. More than that trains customers to ignore you.
Should a failed payment email offer a discount?
Not at first. Most failed payments are involuntary, so the customer usually just needs the update link, and discounting that group gives away margin for nothing. Save incentives for the win-back email after cancellation, where the customer has to make an active choice to return and a nudge genuinely helps.
Can I automate dunning emails on Shopify?
Yes. Subscription apps with built-in dunning handle the whole sequence: they retry the card on a schedule, send a recovery email after each failed attempt, and stop everything the moment a payment succeeds. subZwallet's smart dunning works exactly this way, pairing automatic retry sequences with recovery emails you can customize to your brand.
