Quick Definition
Dunning is the process of systematically communicating with customers to recover failed payments. The term comes from the 17th-century verb "to dun," meaning to make persistent demands for payment.
In modern subscription businesses, dunning refers to automated email and SMS sequences that notify customers of payment failures and guide them to update their payment method.
Related: Dunning prevents involuntary churn, which accounts for 20-40% of all customer churn.
Prevention vs Recovery: While dunning recovers after failure, pre-dunning prevents failures by alerting customers when their card is about to expire. Compare the two approaches →
How Dunning Works
The Dunning Process
- Payment Fails - Stripe/processor declines the charge
- Detection - System identifies the failure in real-time
- Smart Retry - Automatic retry based on failure type
- Customer Notification - Email/SMS sent with update link
- Follow-up Sequence - Additional reminders over days
- Resolution - Customer updates card OR subscription cancels
What Triggers Dunning
Dunning activates when recurring payments fail due to:
- Expired credit cards
- Insufficient funds
- Bank declines
- Lost/stolen card replacements
- Network errors
Why Dunning Matters
The Numbers
| Without Dunning | With Dunning |
|---|---|
| 15-20% recovery rate | 60-80% recovery rate |
| Manual follow-up required | Fully automated |
| Lost revenue walks away | Revenue automatically recovered |
Revenue Impact Example
For a company with $100,000 MRR and 7% failed payment rate:
| Scenario | Monthly Recovery |
|---|---|
| No dunning | $1,400 |
| With dunning | $4,900 |
| Difference | $3,500/month |
That's $42,000/year in recovered revenue.
Dunning vs Collections
| Dunning | Collections |
|---|---|
| Automated, friendly | Manual, formal |
| Immediate after failure | After extended non-payment |
| Customer retention focus | Debt recovery focus |
| Email/SMS | Letters, calls, agencies |
| SaaS subscriptions | Invoiced services |
Dunning is proactive and retention-focused. Collections is reactive and recovery-focused.
Elements of Effective Dunning
1. Timing
The dunning sequence timeline matters:
| Day | Action |
|---|---|
| 0 | First notification (gentle) |
| 2-3 | Follow-up with value reminder |
| 5-6 | Urgency increase |
| 7-10 | Final warning |
| 11-14 | Cancellation |
Too aggressive = annoyed customers. Too slow = lost recovery window.
2. Channels
| Channel | Open Rate | Response Rate | Best For |
|---|---|---|---|
| 20-30% | 5-10% | Detailed info, links | |
| SMS | 90%+ | 30-45% | Urgency, quick action |
| In-app | Varies | High if seen | Active users |
Multi-channel dunning (email + SMS) recovers 40% more than email alone.
3. Tone
Avoid:
- Aggressive language
- Blame or accusation
- Technical jargon
- Multiple CTAs
Use:
- Helpful, friendly tone
- Clear explanation
- Single call-to-action
- Empathy for the situation
4. Payment Update Experience
Every dunning message should include:
- Pre-authenticated link - No login required
- Mobile-optimized page - Most opens are mobile
- Clear instructions - What to do and why
- Support option - In case of issues
Dunning Email Best Practices
Subject Lines That Work
| Approach | Example | Open Rate |
|---|---|---|
| Helpful | "Quick update needed for your account" | 25-30% |
| Personal | "[Name], we need your help" | 28-32% |
| Avoid | "PAYMENT FAILED - ACTION REQUIRED" | 10-15% |
Email Structure
- Greeting - Personal, not robotic
- What happened - Clear, no blame
- Why it matters - What they'll lose
- One CTA - Prominent update button

Smart Retry Strategies

| Network Error | Retry immediately | Within minutes |
| Do Not Honor | Retry once | 3-5 days later |
Combining smart retries with dunning maximizes recovery.

3. Too Many Clicks
Login required, multiple pages, confusing forms = drop-off.
4. Wrong Timing
Too fast = spam. Too slow = customer already left mentally.
5. No Tracking
Can't improve what you don't measure.

Personalization increases response rates by 20-30%.
