How to Build a Churn Prediction Model That ActuallyWorks
As a marketing software provider, one of the most critical metrics that can make or break your business is customer churn. Losing customers is costly—not just in revenue but in the lifetime value and word-of-mouth potential they carry.
At Fostio, we understand how hard it is to acquire a customer. That’s why we believe it’s even more important to retain them.

What Is Churn Prediction?
Churn prediction is the process of identifying users who are at risk of canceling or stopping the use of your product or service. By using historical and behavioral data, businesses can forecast churn before it happens—and act to prevent it.
Churn isn’t just about numbers. It’s about understanding user intent, friction, and engagement patterns.
If you know why users leave, you can design interventions to make them stay.
Why Churn Prediction Is Critical for SaaS
Churn prediction empowers your team to:
React early to at-risk users
Personalize retention campaigns
Improve onboarding and engagement workflows
Increase revenue predictability
Key Metrics and Data Points for Churn Prediction
Before you build a churn prediction model, you need the right data. Here are the most important churn indicators to track in Fostio (and how you can gather them):

1. Product Usage Behavior
This is the most direct indicator of whether a customer is getting value from Fostio. If users are logging in less often or not utilizing key features, it’s usually a sign they’re on the path to churn.
Key Metrics to Track:
Frequency of Logins
Daily, weekly, or monthly login counts.
A sharp decline in login frequency is often a precursor to churn.
Example: Users logging in less than twice a week are 40% more likely to churn.
Number of Emails or Campaigns Sent
If a user signs up but never launches a campaign, that’s a red flag.
Consistent campaign creation indicates healthy usage.
Usage of Automation, Popups, or Landing Page Builders
Track which features are being used and how often.
Power users often adopt multiple features, while churn-prone users may only explore one.
Drop-off Points in the User Journey
Identify where users get stuck or abandon a process (e.g., during onboarding or campaign setup).
Integrate tooltips or support prompts at high drop-off points to re-engage users.
Pro Tip: Fostio’s built-in analytics lets you create user cohorts and map feature usage to lifecycle stages.
2. Customer Demographics and Plan Type
Understanding who your users are helps you identify which segments are most likely to churn. Some user types naturally have higher turnover rates.
Key Variables:
Business Type: Small Businesses vs. Agencies
Agencies may have higher lifetime value but expect more features and support.
Solopreneurs or small businesses may churn due to budget or simplicity needs.
Trial Users vs. Paid Subscribers
Trial users often churn due to lack of onboarding or failure to experience quick wins.
Paid users may churn if they don’t perceive continued value or hit feature limitations.
Billing Type: Monthly vs. Annual
Monthly subscribers are more likely to churn because the cost is frequent and immediate.
Annual users are stickier but need sustained engagement to renew.
Actionable Tip: Tailor onboarding and support flows differently for agencies vs. startups. Fostio’s CRM tagging can help automate this segmentation.
3. Support and Feedback Signals
How users interact with your support team and what they say in surveys often foreshadow their churn intent.
Key Indicators:
Number of Support Tickets
A high number can indicate friction points.
A sudden spike in tickets followed by silence could mean a user is disengaging.
Time to Resolution
Long response times often lead to frustration.
Users who don’t feel supported are much more likely to leave.
Net Promoter Score (NPS)
Scores range from 0–10, with detractors (0–6) being at high risk of churn.
Use NPS to trigger retention workflows (e.g., call high-risk users, offer concierge onboarding).
Customer Satisfaction (CSAT)
A dip in CSAT scores after ticket resolution can point to dissatisfaction with support or product limitations.
Pro Tip: Use Fostio to send in-app NPS/CSAT surveys and tag responses to the user profile for dynamic churn modeling.
4. In-App Behavior
Behavior inside your platform—how users navigate, click, and interact—reveals hidden churn cues even before they open a support ticket.
Key Indicators:
Click Patterns
Are users exploring multiple areas of the platform or bouncing around?
Short, erratic click patterns suggest confusion or lack of direction.
Time Spent on Each Module
Spending consistent time in specific modules (e.g., automation builder) = engaged.
Very short or declining time per session = disengagement.
Abandoned Campaigns or Workflows
Track campaigns that were started but never launched.
Use automated reminders or embedded checklists to guide users back.
Interactions with Onboarding Tours
Did they skip onboarding tutorials?
Did they complete the guided checklist?
Users who complete onboarding are significantly more likely to stick around.
Pro Tip: Fostio’s journey tracking shows funnel drop-offs, helping you insert contextual help or nudges in real-time.

How to Build a Churn Prediction Model
Here’s a practical 3-step process to predict churn effectively:

Step 1: Prepare Your Data
Before you can predict churn, you need to build a solid foundation of clean, reliable data. The quality of your data will directly impact the accuracy of your churn prediction model.
🔹 What to Include in Your Dataset
User Profiles
User ID, email address, company name
Plan type (free, trial, premium, enterprise)
Signup date and billing cycle
Industry and business size (if applicable)
Role of the user (e.g., marketer, agency, CMO)
These fields help you segment users by type and reveal which customer personas are most likely to churn.
Behavioral History
Number of logins in the past week/month
Last login date
Number of marketing campaigns created
Features used (landing pages, automations, popups, etc.)
Actions completed (e.g., publishing a campaign, connecting a domain)
This gives insight into how deeply a user is engaging with Fostio.
Engagement Metrics
Session duration
Frequency of feature usage
Number of support interactions
Onboarding progress (e.g., checklist completion)
Email open/click rates if they use Fostio for campaigns
These metrics show how invested a user is in your platform.
Churn Status (Label)
Binary field:
1
for churned,0
for activeDefine churn as cancellation, downgrade, or inactivity for a set period (e.g., 30 days)
This is the target variable your model will learn to predict.
Clean and Normalize the Data
Once you’ve collected the data:
Remove duplicates and fix missing values
Example: Replace missing login counts with
0
or impute values using averages
Standardize units and formats
Convert dates to consistent formats and calculate time-based metrics like “days since last login”
Normalize numerical features
Scale variables like “number of sessions” or “campaigns created” so they’re on the same scale
If you’re using Fostio, much of this data is already structured and available in the analytics dashboard or can be pulled via API integrations to external BI tools like Tableau or Google BigQuery.
Step 2: Analyze Patterns (Exploratory Data Analysis - EDA)
With clean data in hand, it’s time to dig into the patterns that lead to customer churn. This is where insights come to life.
🔹 Key Questions to Explore
What behaviors are common among churned users?
Are they logging in less often?
Do they stop using specific modules (e.g., automation builder)?
Do they skip onboarding steps?
What do loyal customers do differently?
Do they consistently publish campaigns?
Are they adopting more than three features?
Are they using integrations like Zapier or HubSpot?
Do feedback scores align with churn?
Is there a strong correlation between low NPS scores and upcoming cancellations?
Do customers who give negative CSAT responses churn within 14–30 days?
Which plan types churn the most?
Are monthly subscribers more likely to churn than annual ones?
Do trial users convert or drop off?
🔬 Tools to Use
Visualization Tools (Fostio’s built-in charts, or tools like Power BI and Looker)
Correlation Matrices to identify strong churn signals
Histograms and Box Plots for behavioral distributions
Time-Series Charts to observe engagement trends over time
This phase helps you understand which features are sticky and which behaviors are red flags. You’re essentially preparing your model to ask: “Which patterns indicate that a customer is about to leave?”
Step 3: Train a Churn Prediction Model
Once you’ve identified patterns, the final step is to train a machine learning model to predict churn.
🔹 Choosing the Right Model
Your choice of algorithm depends on your team’s technical expertise and the complexity of your dataset:
We recommend starting simple—a logistic regression model can already provide powerful insights if your data is clean and labeled.
How to Train the Model
Split Your Dataset
Use 70% of your data to train the model
Reserve 30% to test and validate its accuracy
Train the Model
Use libraries like scikit-learn (Python) or AutoML platforms like Google Vertex AI
Input features: usage frequency, plan type, NPS, etc.
Output: probability of churn (between 0 and 1)
Evaluate the Model
Metrics to monitor: Accuracy, Precision, Recall, F1 Score, ROC-AUC
A good model should accurately flag churn-risk users before they leave
Deploy the Model
Integrate predictions into your CRM or marketing automation flow
Send alerts to Customer Success or trigger proactive campaigns in Fostio
