Ultracor case study

How Klaviyo was credited with 68% of store revenue

A deliverability, segmentation and lifecycle rebuild that untangled overlapping flows and turned email, SMS and campaign planning into a connected retention engine.

Ultracor already had the product and visual potential

What it did not have was a retention system capable of protecting inbox health, separating customers by context and moving them deliberately toward the next purchase. Kaysun began working with Ultracor in October 2024 and rebuilt the program around deliverability, segmentation, campaign planning and lifecycle behavior.

The starting point

The problem was not email volume. It was coordination

The account was sending email, but the design, deliverability, segmentation and automation layers were pulling in different directions.

Creative did not match the quality of the brand
Deliverability and inbox placement were weak
Too many emails landed in the Promotions tab
High bounce rate weakened list health
No dependable segmentation framework
No consistent campaign strategy
Flows overlapped and competed with one another
No sunset journey for disengaged subscribers
No complete win-back system
No connected path toward repeat purchase

Every extra send was amplifying an uncoordinated system.

The account needed fewer collisions, clearer customer states and a deliberate path back to purchase.

Retention architecture

One system. Four essential layers

Kaysun rebuilt the program so the message, recipient, timing and next step supported one another.

Deliverability

Reduce list risk, manage bounce and suppression behavior, and rebuild the conditions required for healthier inbox placement.

Segmentation

Group subscribers by engagement, behavior and purchase context instead of treating the whole database the same.

Flow repair

Untangle overlapping automations, rebuild triggers and exclusions, and make each flow responsible for a defined moment.

Winback + sunset

Create a recovery path for lapsed customers and a controlled exit for subscribers who no longer engage.

The emails finally looked like Ultracor

Kaysun gave the program a stronger visual standard without losing the clarity required to sell.

Connected execution

The calendar, segments and flows worked as one

The goal was a customer journey that could improve repeat purchase behavior and customer lifetime value, not a pile of isolated campaigns.

Why this mattered commercially

More returning customers meant the retention system was doing more after the first order – giving the brand a stronger backend to support customer acquisition.

Why the flow rebuild mattered

Automation went from an afterthought to a real revenue layer

Defined jobs replaced overlapping logic

Each automation received a clearer trigger, exclusion and role in the customer journey. Win-back handled lapse. Sunset protected list health. The remaining flows supported the next best customer action.

The two dashboards show different calendar windows and are included as directional account context, not as a controlled like-for-like experiment.

What changed

The program stopped competing with itself

1

Inbox health

List quality and deliverability became operating priorities.

2

Customer context

Segments determined who received each message.

3

Lifecycle control

Campaigns and flows supported the next customer decision.
