Customer Retention

How personalized marketing campaigns are mapped to segmented audience groups

Business Problem

A subscription-based e-commerce company was experiencing declining customer retention despite strong initial acquisition rates. While they had amassed significant customer data, the lack of structured segmentation and insight-driven engagement meant customers received generic messaging, leading to decreased repeat purchases and increased churn. The company needed a way to understand customer behavior better and implement tailored strategies to improve retention.

Key challenges:

  • Fragmented Customer Data: Customer behavior, purchase history, and interaction data were siloed across CRM, website, and email marketing tools.

  • Lack of Segmentation Strategy: Customers were grouped only by broad categories like geography or purchase recency, missing deeper behavioral insights.

  • Generic Messaging: One-size-fits-all campaigns led to low engagement and reduced loyalty from high-value customers.

  • Ineffective Retention Tactics: The company lacked a systematic way to identify churn risks and deliver timely retention offers or interventions.

The Approach

To reverse churn trends and drive repeat engagement, Curate worked with the company to build a robust data infrastructure and implement a comprehensive audience segmentation framework powered by machine learning. The result was highly personalized customer experiences based on predictive insights, leading to improved retention and long-term customer value.

Key components of the solution:

  • Discovery and Requirements Gathering:

    Curate partnered with stakeholders from marketing, product, and analytics teams to understand current data use and retention workflows. Key requirements included:

    • Integrate customer data sources for unified analysis

    • Build behavior-based segmentation models

    • Predict churn likelihood using historical and behavioral data

    • Enable targeted retention campaigns across digital channels

  • Data Segmentation and Analytics Implementation: 

  • Data Consolidation: Unified data from CRM, website, mobile app, and support interactions using ETL pipelines and stored it in a cloud-based warehouse.

  • Behavioral Segmentation: Using clustering algorithms (e.g., K-Means, DBSCAN), customers were grouped based on metrics such as frequency product categories browsed/purchased, and customer support usage.

  • Churn Prediction Models: Machine learning models (random forest, logistic regression) were trained to flag customers at high risk of churn based on inactivity, drop in purchase frequency, or dissatisfaction signals.

  • Personalized Campaign Mapping: Each segment was mapped to tailored campaign strategies, including re-engagement emails, loyalty rewards, and exclusive offers.

  • Process Optimization and Campaign Activation:

    • Automation Triggers: Segment-specific automation flows were created (e.g., cart abandoners received personalized nudges, inactive users were offered time-limited discounts).

    • Dynamic Content Delivery: Messaging was adapted in real-time to reflect user preferences and lifecycle stage, using tools like HubSpot and Braze.

    • A/B Testing & Feedback Loops: Regular experimentation and performance feedback refined targeting, offers, and messaging.

  • Stakeholder Engagement & Change Management:

    • Cross-Team Enablement: Marketers, product managers, and CRM teams were involved in use-case prioritization and campaign design.

    • Training: Hands-on training sessions were conducted to ensure teams could interpret segmentation outputs and align content strategies accordingly.

    • Iterative Development: Feedback loops ensured the segmentation logic and campaign rules evolved alongside customer behaviors.
