The identity gap: How marketers perceive success and where performance breaks down

Why marketing can seem like it’s working—until it’s put to the test

Most marketers believe their marketing is working. Campaigns launch, audiences are reached and results appear sufficient on the surface. But as customer journeys grow more complex and expectations rise, that confidence becomes harder to maintain.

New research from the American Marketing Association and Epsilon Pulse reveals a clear gap between perceived success and actual performance.

This gap in perception often remains hidden until marketers are asked to do more: reach new audiences, deliver personalized experiences and prove impact. At that point, what once felt effective begins to break down. The research shows that this breakdown is often tied to the absence, or incomplete use, of identity resolution.

3 key findings from identity research

A new survey of 203 business-to-consumer marketers fielded by the American Marketing Association reveals a consistent pattern: marketers who use identity resolution report stronger performance across the areas that matter most.

1. Performance breaks down during audience growth

Marketers feel confident working with known customers, but that confidence declines when they try to reach new audiences. Even when prospects can be identified, consistently reaching them proves far more difficult without connected data.

2. Identity users outperform across core marketing capabilities

Marketers using identity resolution are significantly more likely to report effectiveness in reaching prospects, delivering personalized experiences and running successful digital campaigns. These differences become most visible as demand for precision and relevance increase.

3. Identity is in place, but not fully realized

While many organizations have adopted identity resolution, its impact is often limited by partial implementation. Identity is frequently applied to only a portion of the marketing stack, leaving gaps in execution, measurement and optimization.

Together, these findings highlight a clear gap between perceived effectiveness and actual performance—and reinforce identity resolution as a critical foundation for closing the gap.

Why identity resolution is becoming essential for modern marketing performance

As marketing organizations scale, expectations continue to increase. Leaders demand clearer results, stronger accountability and more efficient use of data. In this environment, “good enough” performance is no longer sufficient.

The research highlights a consistent pattern: marketers can operate without identity under simpler conditions, but when it is time to scale, growth and complexity expose its absence. Identity resolution becomes the foundation that connects data, improves visibility and enables sustained performance over time.

Understanding this shift is critical for any organization looking to close the gap between how their marketing appears to perform and what it actually delivers.
