How PlusSquire Drove a +42% Email Revenue Lift & 3.8× Flow ROI for a DTC Fashion Brand

Replacing default 2-step templates with a 7-flow behavioral lifecycle engine, dynamic size-in-stock blocks, and margin-safe checkout splits that turned Klaviyo into their #1 profit channel.

Client: Women’s Contemporary DTC Apparel Brand
Implementation Window: 21 Days
Core Result: 58.2% Avg. Flow Open Rate
Attributed Email Revenue Lift +42% Within 45 Days of Flow Relaunch
Automated Flow ROI 3.8× Higher Revenue Per Recipient vs Legacy
Average Flow Open Rate 58% Across All 7 Core Lifecycle Flows
Strategic Insight: Apparel shoppers abandon carts primarily over fit uncertainty and shipping questions—not just price. By adding dynamic size/fit guides, real customer measurements in UGC blocks, and splitting first-time visitors from repeat VIPs, we lifted checkout recovery without giving away unnecessary discounts.

The Challenge: High Ad Spend, Leaky Post-Click Retention

This DTC fashion brand was scaling paid social spend on Meta and TikTok, driving tens of thousands of monthly store visitors—but their Klaviyo account was still running the basic starter templates they set up three years earlier.

They had no custom Added to Cart trigger (missing shoppers who added items to the slide-cart without starting checkout), their Welcome Series consisted of a single 10%-off email, and every post-purchase buyer received the exact same generic receipt regardless of whether they spent $48 or $420.

What We Built Inside Klaviyo & Shopify

Pillar 01 · Welcome & Zero-Party Fit Quiz 61.4% Open Rate

4-Email Editorial Welcome Journey

Upgraded their pop-up to capture style preference in Step 1, then branched the Welcome Series dynamically so dress shoppers saw seasonal dresses while activewear shoppers saw performance sets—coded in crisp, dark-mode-safe HTML.

Pillar 02 · 3-Tier Abandonment Ladder +114% Cart Recovery

Browse, Added-to-Cart & Checkout Splits

Installed custom Shopify AJAX cart tracking so Klaviyo captured Added-to-Cart events immediately. Built conditional splits at $125 AOV threshold so high-margin carts received free express shipping or tiered gifts rather than blanket percentage discounts.

Pillar 03 · Post-Purchase Cross-Sell & Sunset +29% Repeat Order Rate

Automated Lookbook Cross-Sell & List Hygiene

Paired every first-time order with a "Complete the Look" dynamic recommendation 14 days post-delivery, while an automated 120-day Sunset Flow kept sender reputation spotless and open rates at 58%.
