Pre-Dunning in 2025: Build a Multi-Channel Workflow That Cuts Involuntary Churn by 15%
Introduction
Involuntary churn is the silent killer of subscription businesses. While you're busy optimizing onboarding flows and feature adoption, up to 70% of your churn stems from failed transactions—customers who never intended to leave but are forced out when a card is declined (Slicker). The numbers are staggering: involuntary churn can represent up to 30% of total customer churn for subscription businesses (Slicker).
But here's the opportunity: unlike voluntary churn, involuntary churn is entirely preventable with the right pre-dunning strategy. A well-orchestrated multi-channel workflow combining email, SMS, push notifications, and in-app alerts can reduce involuntary churn by 15% or more. The key is reaching customers before their payment fails, not after.
In 2025, successful subscription businesses are moving beyond reactive dunning to proactive prevention. This comprehensive guide will show you how to build a pre-dunning workflow that combines industry best practices with cutting-edge automation to keep your customers subscribed and your revenue flowing.
Understanding the Pre-Dunning Landscape in 2025
The Scale of the Problem
The involuntary churn crisis is worse than most businesses realize. Recent analysis shows that involuntary churn accounts for as much as 34% of the overall churn rate (Drips). In some industries, decline rates reach 30%—and each one is a potential lost subscriber (Slicker).
Perhaps most alarming is this statistic: a staggering 62% of users who hit a payment error never return to the site (Slicker). This means that once a payment fails, you've likely lost that customer forever unless you intervene proactively.
The Eight Personality Types of Churned Users
To build effective pre-dunning workflows, you need to understand who you're trying to save. The 8 Personality Types of the Churned User framework reveals the diverse reasons behind payment failures (Slicker):
The 'New Card, Who Dis?' User: Updated their payment method but forgot to update your service
The 'Card Left the Building with Bob' User: Company card holder left, taking payment access with them
The 'False Fraud Flag' User: Legitimate transaction flagged by overzealous fraud detection
The 'Banking Adventure' User: Temporary account issues or bank maintenance
The 'Time Zone Traveler' User: International transactions triggering security blocks
The 'Temporary Card Tango' User: Using temporary or virtual cards that expired
The 'Seasonal Subscriber' User: Intentionally pausing during off-seasons
The 'Actually Voluntarily Churned' User: Decided to cancel but never completed the process
Understanding these personality types is crucial for building better retention strategies (Slicker). Each type requires a different pre-dunning approach and messaging strategy.
The Rise of AI-Powered Prevention
The AI sector in 2025 has seen unprecedented acceleration, with compute scaling 4.4x yearly and LLM parameters doubling annually (SentiSight). This technological advancement is revolutionizing payment recovery, with machine-learning engines now able to predict the perfect moment, method, and gateway for each retry, lifting recovery rates 2-4x above native billing logic (Slicker).
Building Your Multi-Channel Pre-Dunning Workflow
Channel Strategy and Timing
The most effective pre-dunning workflows use multiple touchpoints across different channels. Based on industry benchmarks, the optimal cadence involves three-to-four messages over 28 days, starting 7-10 days before the renewal date.
Recommended Channel Sequence:
Day -7: Email notification with payment update link
Day -3: SMS reminder with direct action button
Day -1: Push notification (mobile app users)
Day 0: In-app alert during active session
Day +1: Final email with urgency messaging
Email: The Foundation Channel
Email remains the cornerstone of pre-dunning communication, offering the space needed for detailed explanations and clear calls-to-action.
Pre-Dunning Email Template 1: Initial Warning (Day -7)
Pre-Dunning Email Template 2: Urgent Reminder (Day +1)
SMS: The Urgency Channel
SMS delivers immediate impact with open rates exceeding 90%. Keep messages concise and action-oriented.
SMS Template Examples:
Push Notifications: The Contextual Channel
Push notifications work best when users are actively engaged with your product. Time these for peak usage hours.
Push Notification Examples:
In-App Alerts: The Conversion Channel
In-app messages have the highest conversion rates because users are already engaged with your product.
In-App Alert Strategy:
Use modal overlays for critical payment failures
Implement banner notifications for upcoming expirations
Provide one-click payment update flows
Show progress indicators during the update process
Advanced Segmentation and Personalization
Segmentation by Decline Codes
Not all payment failures are created equal. Segment your pre-dunning campaigns based on specific decline reasons:
Insufficient Funds (Decline Code: 51)
Messaging: "Temporary payment issue"
Timing: Retry in 3-5 days
Channel: Email + SMS
Tone: Understanding and helpful
Expired Card (Decline Code: 54)
Messaging: "Card expired - quick update needed"
Timing: Immediate action required
Channel: All channels
Tone: Urgent but supportive
Fraud Suspected (Decline Code: 59)
Messaging: "Security verification needed"
Timing: Immediate with manual review
Channel: Email + phone call
Tone: Security-focused and reassuring
Fraud-based declines are up 41% according to recent data, making this segmentation increasingly important (Slicker).
Customer Value Segmentation
Tailor your pre-dunning intensity based on customer lifetime value:
High-Value Customers (Top 20% by LTV)

Frequently Asked Questions
What is pre-dunning and how does it reduce involuntary churn?
Pre-dunning is a proactive approach that alerts customers before their payment fails, rather than after. By implementing multi-channel notifications (email, SMS, push, in-app) before the payment attempt, businesses can reduce involuntary churn by up to 15%. This strategy addresses the fact that up to 70% of subscription churn stems from failed transactions, not customer dissatisfaction.
Which channels are most effective for pre-dunning notifications?
The most effective pre-dunning strategy uses a multi-channel approach combining email, SMS, push notifications, and in-app alerts. SMS has proven particularly effective for urgent payment updates, while email works well for detailed instructions. Push notifications provide immediate visibility, and in-app alerts catch users during active sessions when they're most likely to take action.
How much involuntary churn can pre-dunning actually prevent?
According to industry data, involuntary churn accounts for as much as 34% of overall churn rates. A well-implemented pre-dunning workflow can reduce this by 15% or more. Given that Churnkey recovered $250 million in revenue in 2024 from failed payments, the financial impact of effective pre-dunning strategies is substantial for subscription businesses.
What are the key components of an effective pre-dunning workflow?
An effective pre-dunning workflow includes: automated triggers 3-7 days before payment attempts, personalized messaging across multiple channels, clear action steps for customers, fallback payment methods, and integration with AI-powered payment recovery systems. The workflow should also include timing optimization and A/B testing to maximize recovery rates.
How does AI-powered payment recovery enhance pre-dunning efforts?
AI-powered payment recovery systems can analyze customer behavior patterns, payment history, and transaction data to optimize pre-dunning timing and messaging. These systems can predict which customers are most likely to experience payment failures and customize the pre-dunning approach accordingly. As highlighted in Slicker's research, AI implementation can significantly improve payment recovery rates when combined with proactive pre-dunning strategies.
What metrics should I track to measure pre-dunning success?
Key metrics include: involuntary churn reduction percentage, payment recovery rate, customer response rate to pre-dunning messages, time-to-resolution for payment issues, and overall revenue recovered. You should also track channel-specific performance (email vs SMS vs push) and customer satisfaction scores to ensure the pre-dunning process doesn't negatively impact user experience.
