The SMS Attribution Challenge

SMS marketing has become a key channel for Shopify brands due to high open rates and direct engagement. However, traditional attribution models frequently omit or misattribute SMS conversions because:

SMS links may lack tracking parameters.

Conversions happen offline or after multiple touchpoints.

Privacy restrictions limit tracking.

This results in an attribution gap where SMS impact is undervalued or invisible.

Why Accurate SMS Attribution Matters

Without reliable measurement, brands risk underfunding SMS campaigns despite strong performance, or misallocating budget to other channels.

Causal Inference Bridges the Gap

Causality Engine estimates the incremental effect of SMS marketing by analyzing aggregate sales data alongside other channels, without requiring explicit tracking.

Benefits

Quantifies true SMS contribution.

Helps refine timing and segmentation.

Integrates seamlessly with Shopify data.

Case Study

A Shopify brand using SMS marketing saw attributed conversions jump from 5% (last-click) to 18% after adopting causal inference, enabling a 40% boost in SMS campaign spend and a 28% increase in overall ROI.
