E-commerce CRO + Retention
The Challenge
Margins squeezed by ads. Returns eating profit. No retention.
A DTC fashion brand was addicted to paid social. Rising Meta and TikTok ad costs were squeezing margins, the store converted inconsistently, returns were high because sizing was confusing on PDPs, and there was no retention engine to bring customers back. Every growth dollar had to come from another ad.

“Heavy Meta + TikTok ad spend driving traffic to a store that converted poorly, with no retention engine to compound the spend.”
Before vs. After
From a thin Shopify store dependent on ads to a CRO-tuned store backed by a lifecycle revenue engine.
What We Did
Fix the fit confusion. Lift the checkout. Build the lifecycle.
Channels
- Shopify store CRO redesign
- PDP sizing & fit guidance
- Email + SMS lifecycle flows
Tools
- Shopify
- Klaviyo (email + SMS)
- Loop / returns tooling
- GA4 + Shopify analytics
Key Tactics
- 01Redesigned product pages with detailed fit guides, model-size references, and customer fit feedback to attack the #1 driver of fashion returns — sizing confusion
- 02Streamlined checkout, added trust + social-proof elements (reviews, UGC) above the fold, and removed friction the analytics data flagged
- 03Built a full lifecycle email + SMS flow stack — welcome, browse abandonment, cart, post-purchase, win-back — in Klaviyo
- 04Introduced a loyalty + rewards offer to grow repeat purchase rate and break the brand's dependence on new-customer paid acquisition
The Results
Every metric moved. Verified in Shopify + Klaviyo + returns data.

Beyond the Numbers
- Lower return rate recovered meaningful margin previously lost to reverse logistics
- Lifecycle flows became a leading, lower-cost revenue channel — not a side note
- Higher repeat rate broke the dependence on rising paid-social CPMs

We were addicted to ad spend. They built a store and a retention engine that finally let us grow on our own customers.
