How a Global Fashion Brand Moved Off Its Legacy ESP to Achieve 31% Conversion Rates

Published : June 17, 2026

If you’ve ever worked in fashion retail, you know that timing isn’t just a metric; it’s the entire customer experience. In a fast-paced market, a delayed campaign doesn’t just mean a dip in engagement; it means missing a seasonal trend, causing an out-of-stock heartbreak, and losing a fleeting moment of impulse that never returns.

For one prominent global fashion retailer, the stakes were high. Their ultimate goal was to build a robust, loyal customer base by providing exceptional experiences, reactivating inactive users, and driving repeat purchases.

This wasn’t a team starting from scratch; they were already running a mature engagement stack. But to act on real-time intent, they realized they couldn’t rely on generic marketing automation. They needed a system that could decide and act in the moment.
That’s where Netcore’s agents stepped in!

The Obstacles: Fragmented Delivery, Gated AI, and Data Blind Spots

Most high-growth consumer brands don’t have a data shortage; they have a signal shortage. This retailer was sitting on massive amounts of behavioral data, but their existing MarTech stack was holding it back.

Before transforming their approach, the marketing team faced several critical roadblocks with their existing customer engagement platform:

  • Separate delivery engines for transactional and promotional email created a disjointed experience, and because they didn’t own the underlying MTA, deliverability was largely out of their hands.
  • Restricted templates and limited creative and interactive options across email, little room to engage customers, or to tailor the platform to how the brand actually worked.
  • Personalization relied on basic in-house algorithms built on past purchase history. The system could explain what had already happened, but it couldn’t predict who was about to buy.

The Turning Point: The brand realized that traditional algorithms were no longer enough. They needed a single, unified platform and a partner who could get them there fast. They chose Netcore, and, in under a month, migrated 75+ complex automated journeys, from browse abandonment and category drop-offs to wishlist and birthday flows, along with their entire user and event data set.

 Netcore’s managed services and customer success team handled the migration end to end, from journey orchestration to template setup, so the switch happened with minimal disruption and at no extra cost.

Enter the Marketing Agents

The retailer didn’t just upgrade their software; they fundamentally changed how their marketing operated by moving onto an Agentic Marketing Platform. Instead of relying on a team to manually pull lists and set static rules, they let AI agents turn behavioral data into real-time decisions and then act on them. Here’s how that played out across their two most important journeys.

Breakthrough 1: Unraveling Data Hiding in Plain Sight 

Once on Netcore, the brand began running a set of high-impact merchandising triggers: low-in-stock, wishlist low-in-price, new-arrival (Monday) drops, back-in-stock, and running-out-of-stock alerts. Each is built to reach a customer at a moment of genuine, time-sensitive intent, using urgency and social proof to turn a saved item into a purchase.

What made them convert was the data behind them. The Audience Agent continuously analyzed behavioral signals, product affinity, browsing behavior, engagement history, and purchase propensity to build far richer, more precise cohorts than static rules ever could. 

The shift was from broad reminders to precision engagement. Instead of repeatedly asking everyone to come back, the brand reached the customers most likely to buy and intervened when it mattered, driving more wishlist recoveries, stronger engagement, and incremental revenue from demand that already existed.

Breakthrough 2: Real-Time Precision (The Birthday Drop)

The brand wanted special occasions to feel like genuine recognition of loyalty, not just another promotion. Using AI-powered decisioning, it turned a standard birthday discount into a personalized experience: an exclusive 25% offer, delivered through app notifications and tailored messages across the customer’s birthday month.

Rather than treating everyone the same, the AI read engagement patterns, purchase history, and affinity signals to judge how each customer was most likely to respond, and timed each message for maximum relevance, adding urgency before the offer expired. What was once a routine discount became a loyalty-building moment that made customers feel recognized, appreciated, and rewarded.

The Results: Autonomous Revenue Growth

The shift from manual rule-setting to agentic orchestration wasn’t just a workflow upgrade; it changed customer behavior and drove real revenue. In just three months, the brand achieved a 31% conversion rate through autonomous wishlist low-in-stock reminder communications.

The Takeaway

Legacy rules engines help you execute what you already know. Agentic AI helps you discover, and act on what to do next.

This brand didn’t switch tools to get a nicer dashboard. They switched so they could stop doing post-campaign archaeology and start acting on intent in real time. By putting AI agents to work on the heavy lifting, they freed their marketing team to act as strategic directors, letting richer data, sharper segmentation, and well-timed merchandising triggers compound into sustained revenue growth.
