Business & Organizational Context

The Engagement Gap

Our product team identified a critical gap in customer engagement that directly impacted Gross Merchandise Bought (GMB). Buyers were missing key updates about their transactions, which led to abandoned purchases and lower retention.

Core Challenges
  • Buyers missing item availability, price drop, and order status updates
  • Notifications felt noisy, generic, and poorly timed
  • Inconsistent delivery across push, email, and in-app channels
  • No clear framework for prioritizing which updates mattered most
Strategic Leadership

The challenge was not adding more notifications — it was rethinking how and when a buyer should hear from us so every message felt earned and useful.

This required establishing
  • A prioritization model for competing notification types
  • Consistent timing and tone across channels
  • Cross-functional alignment with growth, engineering, and trust & safety
Product Discovery

Research revealed buyers didn't want fewer notifications — they wanted more relevant ones:

  • Missed price drops on watched items
  • Unclear order status updates
  • Notification fatigue from irrelevant alerts
  • Low trust in push notification timing

This shifted the initiative from "send more alerts" to "send the right alert, at the right moment."

Research Activities
Conducting surveys and interviews with buyers
  • Diary studies with active buyers
  • Notification preference surveys
Identify core buyer segments
  • Deal Hunters
  • Repeat Sellers' Buyers
  • First-time Buyers
Utilize card sorting to identify priority signals
  • Price drops, availability, and shipping updates
  • Order status vs. marketing messaging
Key Insights
1. Volume wasn't the problem. Relevance was.

Buyers didn't mind notifications — they minded irrelevant ones crowding out the ones that mattered.

2. Timing mattered as much as content.

A price-drop alert sent an hour late felt like noise, not help.

3. Buyer segments needed different cadences.

Deal hunters wanted more alerts; first-time buyers wanted fewer, clearer ones.

4. Trust compounded over time.

Consistently useful notifications increased tap-through rates on future alerts.

Strategic Design Decisions

Some stakeholders prioritized notification volume as an engagement lever, while buyers consistently prioritized relevance, timing, and trust.

I advocated for a prioritization model and per-segment cadence to protect trust while still driving engagement.

This required difficult tradeoffs between
  • Engagement volume vs. buyer trust
  • Personalization vs. simplicity
  • Growth team goals vs. buyer experience
  • Short-term taps vs. long-term retention
I prioritized
  • A notification priority framework
  • Segment-based cadence rules
  • Clear, actionable notification content
  • Consistent timing across channels
  • Reusable notification templates
  • Opt-in controls for buyer preference
Buyer Persona
Seller Persona
Design Evolution · Notification Center
Initial Direction

A single flat feed exposed every notification type in one undifferentiated list.

Problem

Buyers struggled to understand

  • Which alerts needed action
  • What was time-sensitive
  • How to mute noisy categories
What Research Revealed

Buyers thought in categories — orders, deals, account — not a single timeline.

Design Shift

We moved to a categorized notification center with per-category controls and priority sorting.

Tradeoff

Added a layer of navigation in exchange for clarity and buyer control.

Design Evolution · Notification Card
Initial Direction

Early concepts packed every available detail into each notification card.

Problem

Buyers scanned past dense cards without registering the one detail that mattered.

Research Insight

A single clear call-to-action outperformed dense, multi-detail cards.

Design Shift — Introduced
  • One primary message per card
  • Visual hierarchy for time-sensitive alerts
  • Single clear call-to-action
  • Standardized card templates by category
Tradeoff

Reduced information density per card to improve scan speed and action-taking.

Design System Experience

A major challenge was standardizing notification content across dozens of teams sending alerts to the same inbox.

I introduced
  • Standardized notification card templates
  • A shared priority/urgency taxonomy
  • Consistent iconography by category
  • Unified timing and frequency rules
  • Reusable copy patterns by notification type

The goal was a notification experience that felt like one coherent voice, not dozens of competing teams.

This significantly reduced inconsistency across push, email, and in-app alerts.

Final Experience

The final experience consolidated fragmented, team-by-team alerts into one coherent notifications system that felt timely and relevant to each buyer.

The system enabled buyers to
  • Catch price drops before they expired
  • Track order status without digging through email
  • Tune which categories they hear from and how often
  • Act on notifications with a single tap

The experience shifted notifications from noisy interruptions toward trusted, timely help.

Business Outcomes & Organizational Impact

The initiative closed a critical engagement gap, giving buyers timely, relevant updates while establishing a shared framework for how eBay teams communicate with buyers.

Strategic Outcomes
  • Reduced missed price-drop and availability alerts, protecting GMB
  • Established a shared notification priority framework across teams
  • Improved trust and tap-through on future notifications
  • Reduced notification fatigue through segment-based cadence
  • Standardized notification templates for faster team onboarding
  • Created a reusable foundation for future notification types
