Case Study 01
Direct Mail Optimization for a National Television Provider
UX research and prototyping to improve customer engagement and reduce costs.
The brief
A major national television service provider had a direct mail piece that consistently outperformed everything else in their mailing schedule, a so-called champion letter, but had no insight into what made it work or how to replicate that success. The ask was twofold: understand what made the champion letter effective at a specific, attributable level, and use those insights to inform a redesign that was cheaper to produce without sacrificing what made it work.
As the lead researcher and designer, I owned the full research lifecycle, from study design and recruitment through moderation, analysis, and synthesis, then transitioned directly into prototyping a redesigned version informed by the findings.
Mixed methods: why both mattered
We combined 25 moderated, in-person in-depth interviews with Tobii eye tracking in the same sessions. Self-reported interview data tells you what people think they noticed. Eye tracking tells you what they actually looked at. Running them together let us validate whether stated preferences aligned with actual behavior, and in several cases they did not, which was the most important finding of the study.
Eye tracking captured the critical first eight seconds of exposure to each of six mailers, the window most predictive of sustained engagement. I analyzed gaze patterns, fixation points, scan paths, and time-on-element data across headlines, imagery, and calls to action.
What the research revealed
01 — Simplicity outperformed complexity
The champion letter had the simplest visual structure of the six pieces: one clear CTA, a single benefit-focused headline, minimal clutter. Eye tracking confirmed it through more efficient gaze patterns and lower time-to-CTA.
02 — Visual hierarchy controlled gaze
The champion letter guided viewers along a predictable Z-pattern scan path: brand mark, headline, primary benefit, CTA, in sequence. Mailers with competing visual elements scattered attention and drove early drop-off.
The divergence finding: participants described two lower-performing mailers as 'visually appealing' in interviews. Eye tracking showed they were dwelling on decorative imagery and consistently missing the CTA. What people said and where they looked were different things, which is exactly why combining methods mattered.
03 — Trust cues were essential
Brand recognition elements, testimonials, and personalized addressing drove positive response. Mailers lacking these read as generic or overly promotional.
04 — Information overload actively hurt
Mailers with more than three CTAs, dense copy, or small fonts were the lowest performers. Participants skipped large text blocks entirely, regardless of informational value.
From research to prototype
I prototyped a redesigned one-page version in Axure: eliminated content eye tracking showed nobody read, restructured layout along the confirmed Z-pattern, retained every trust element, and reduced to a single CTA.

Reflection
The constraint of reducing cost without reducing impact forced the design toward greater simplicity, which turned out to be exactly what the research recommended anyway. The cost problem and the engagement problem had the same solution.
