As the lead designer at Cordial, a marketing automation platform for cross-channel campaigns, I spearheaded the Audience Builder project, creating a flexible tool for scalable audience segments across email, SMS, and in-app notifications. Over 10-12 months, I drove the initiative for marketers in e-commerce and beyond, while mentoring newly joined designers, using the project to help foster their growth in our design process.

Enhance audience segmentation with intuitive, canvas-based interactions, enable nesting of saved groups, and optimize backend scalability to improve campaign precision and user efficiency within Cordial's marketing workflows.
Create a visual, dynamic side panel layout to speed up segment creation with drag-and-drop, fast clicks, and flexible repositioning for users of all skill levels.
Introduce non-disruptive nesting of existing saved audiences, empowering advanced layering without affecting originals or requiring relearning.
Scale backend to handle large datasets seamlessly, reducing silos and enabling faster, more accurate targeting across email, SMS, and in-app channels.

Marketers struggled to scale with rising data volumes, delaying campaigns for emails, SMS, and in-app alerts. Backward compatibility was key to skip retraining. Users sought greater control over segmentation, but the platform relied on an outdated code modal limited to advanced users proficient in JSON, complicating rule and ruleset creation. This dependency slowed processes and forced frequent customer support requests, highlighting the need for a simpler, faster interface accessible to all without technical barriers.
User interviews & CS support time on manual metrics shaped a visual UI for diverse personas. Wireframes guided it, prototypes validated, testing refined results.
Couldn't handle scaling large queries, leading to delays when segmenting big contact lists.
No nesting for saved audiences, making advanced campaign logic more complicated.
Custom metrics were for advanced users with JSON knowledge. Customer support reliance and turnaround time.
These findings shaped personas (e.g., "Jr. Marketer" vs. "Mid-Tier Campaign Analyst" vs. "Senior Marketing Manager") and validated assumptions, ensuring designs addressed real challenges like varying skill levels within Cordial.
Demographics: Entry-level marketer, 22-30, recent grad or 1-3 years experience, new to Cordial, manages basic campaigns for small audiences.
Goals/Needs: Quickly create simple segments for promos or abandonments using visual tools, with minimal scripting.
Pain Points: Overwhelmed by complex queries, frequent grouping errors, and heavy reliance on help for adjustments.
Behaviors: Enjoys interactive drag-and-drop features, prefers a more automated approach.
Design Influence: Highlighted user-friendly visual aids and streamlined workflows.
Demographics: Mid-career specialist, 30-40, with 4-7 years in digital marketing, average Cordial user, handles mid-scale targeting and group partnerships.
Goals/Needs: Creates moderately layered segments with instant edits and fast previews, blending channels for effective outreach.
Pain Points: Slowdowns from outdated systems, and issues linking without changing campaigns.
Behaviors: Mixes visual tweaks with basic coding, values speed in team edits, tests mergers but seeks reliability.
Design Influence: Shaped hybrid visual and coding tools with error fixes, reducing stress for mid-level tasks.
Demographics: Seasoned marketer, 40-55, 8+ years in marketing ops, heavy Cordial user, manages big campaigns and multi-group targeting.
Goals/Needs: Build and save complex queries with flexible links, ensuring safe edits and smooth channel integration.
Pain Points: Few connection options, campaigns split across platforms, and edits risking existing setups.
Behaviors: Relies on quick keys and shortcuts, focuses on precision and scalability, and frequently links segments for promotions.
Design Influence: Pushed for features like quick linking and real-time hints, boosting overall performance without risking the platform's stability.
I examined leading competitors in audience segmentation for marketing automation platforms like Cordial, including Mailchimp, Marketo, Braze, and Iterable. This analysis uncovered notable gaps in scalability and nesting capabilities that Audience Builder was designed to address.
Mailchimp had roughly 60% market share in small-business email automation with its accessible UI, yet it struggled with advanced segmentation scalability for larger audiences.
Marketo, a preferred choice for mid/large B2B companies, offered robust capabilities but featured a clunky UI for non-technical users and limited real-time nesting, while Braze, known as a cross-channel leader, came with higher costs and a steeper learning curve.
Tools like Braze and Iterable provided timely multi-channel targeting but had restrictions on nested audience groups and backend performance for larger datasets.
Many users, especially non-technical users favored Mailchimp for simplicity but wanted better nesting capabilities for dynamic campaigns. They also favored a more visual, hands-on experience, highlighting the need for drag-and-drop functionality and the ability to quickly reorder segments.
During the initial exploration phase, we collaborated with stakeholders and clients to present low-fidelity wireframes, gathering valuable feedback on the drag and drop concepts which helped refine and guide the eventual high-fidelity designs.
Iterative testing with internal teams and client groups (4-5 participants), plus live reviews for UI tweaks.
Strong approval. Testers praised the "smooth yet powerful" setup, with quick simple builds. Reduced support tickets by enabling self-service.
Increased adoption post-launch; positive feedback on nesting capabilities and interactive UI.
More individual control over segmentations with less reliance on CS support.
This prototype was used to monitor how users would interact with the new drag and drop UI. Users were asked a series of questions below during recorded sessions.
This project reinforced the value of iterative UX refinement, balancing scalability and user intuition for effective cross-channel targeting. Working closely with backend developers to tackle outdated components, compatibility issues, and nesting challenges not only resolved these technical hurdles but also sparked innovative canvas interactions that minimized modal disruptions.
In retrospect, I'd emphasize broader A/B testing early on to measure UI effects on campaign speed. Ultimately, Audience Builder shows how empathetic design turns segmentation tools into seamless assets for marketers.

The final Audience Builder project transformed segmentation by boosting efficiency and effectiveness, opening the feature to all skill levels from its original JSON syntax editor for advanced users. This user-focused redesign spurred a significant rise in audience segment creation, enhancing adoption across Cordial’s platform.
Cut segment creation time by roughly 40%, enabling marketers to build audiences much faster and more efficiently.
Reduced support ticket volume by roughly 55%, empowering self-service and cutting custom segmentation delays.
Boosted targeting accuracy by 30%, enhancing conversion rates for email, SMS, and in-app campaigns with greater impact.
