Project Overview

Separating Campaign Impact from Natural Behavior

The client needed to understand how much of its CRM-driven revenue and engagement was truly incremental, rather than behavior customers would have shown anyway.

  • Measurement Ambiguity
    Without a rigorous framework, it was impossible to isolate campaign-driven engagement and purchases from natural customer behavior.
  • Multi-KPI Complexity
    Performance needed to be evaluated simultaneously across revenue, conversion, engagement, and lifecycle metrics.
  • Attribution Uncertainty
    Existing reporting couldn't confirm whether observed lift was statistically significant or simply noise.

Execution

Building a Holdout-Based Incrementality Framework

We designed a controlled measurement approach that could isolate the CRM campaign's true effect from baseline behavior.

  • Treated vs. Holdout Design
    Built an incrementality framework comparing a treated audience against a matched holdout group.
  • Eligibility & Consent Validation
    Verified audience eligibility and CRM opt-in status to ensure clean, compliant test groups.
  • Attribution Windows
    Measured performance across both 3-day and 7-day attribution windows to capture short- and mid-term effects.
  • Statistical Rigor
    Analyzed incremental lift and statistical significance across revenue, transactor, engagement, and lifecycle KPIs.

Results

A Validated, Scalable Growth Channel

The analysis confirmed CRM as a genuine growth driver and gave the client a defensible, data-backed view of campaign performance.

  • Revenue Impact
    Delivered statistically significant uplift in Full Game Revenue and Full Game Transactors of +5–7%.
  • Engagement Gains
    Increased Add-On Revenue by +3–5% while driving measurable improvements in Gameplay and Wishlisting engagement.
  • Strategic Confidence
    Validated CRM as an effective growth channel and provided actionable insight to optimize future targeting, investment, and campaign strategy.

With incrementality built into the measurement approach, the client can now scale CRM investment based on proven, not assumed, impact.
