Case Study:
Walmart - Email Design System & Templates
Role: Director of Design
Company: Walmart eCommerce
Team: Internal, cross-functional (Design, Engineering, Marketing, CRM)
Duration: 3 weeks
Background
Email at Walmart was critical for both marketing and essential customer communications (e.g., cart reminders, order confirmations, shipping updates). Over time, these had evolved in silos: marketing emails were custom-coded per campaign, while triggered emails used legacy engineer-built templates. The result was inconsistent experiences, slow iteration, and high maintenance overhead.
I led the design of a unified, modular email system that aligned UX, visual standards, and operational workflows across teams — treating email as a scalable product surface rather than ad-hoc HTML assets.
The Problem
Walmart’s email ecosystem lacked a unified design system. Custom-coded marketing emails and outdated triggered templates created fragmentation, slow production cycles, and dependency on engineering for routine updates.
How might we design a modular email system that supports both marketing and triggered communications—enabling faster execution, reducing engineering overhead, and delivering consistent, high-quality experiences at scale?
The Process
Discovery & Benchmarking
I audited the existing email ecosystem and identified fragmentation points. To inform system requirements, I benchmarked email systems at Target, Home Depot, and Amazon for reusable patterns, modular layouts, and governance strategies.
Cross-Functional Alignment
Early partnerships with marketing and engineering clarified key triggers (browse, cart, order, fulfillment), content requirements (transactional/legal language), segmentation needs, tooling constraints, and edge cases to ensure the system matched operational realities.
We also used our personas in conjunction with the marketing segment demographics to inform our decision making throughout the process.
Atomic System Design
I defined an atomic, component-based system with flexible, responsive modules that served both promotional and triggered needs, reducing bespoke coding and enforcing consistency across millions of sends.
Test and Iterate We used the current email sends to test components for usability, get design feedback and roll-out the new styles.
Results & Learnings
The unified email system delivered measurable improvement in both efficiency and engagement:
By shifting from custom-coded templates to a modular system, teams gained autonomy, reduced bottlenecks, and elevated UX consistency across high-volume customer communications.
