Everlane is a modern apparel brand known for its commitment to quality, transparency, and doing right by its customers. With a strong ecommerce presence and customer-friendly policies, returns are a natural part of the experience and a key part of keeping customers happy.

But those same policies can attract a small, damaging group: return fraudsters and organized bad actors who exploit generous return workflows, carrier systems, and operational blind spots. For Everlane, one significant source of return fraud was Fake Tracking ID (FTID) fraud.

Wyllo, in partnership with Happy Returns, a UPS company, helped Everlane achieve the following key results:

• Tens of thousands of dollars in FTID-based fraudulent returns were prevented within the first two months. Wyllo quickly surfaced and stopped a problem the team hadn’t been able to quantify before.

• Hours of manual investigation are avoided each week. Instead of digging through UPS invoices and one-off cases, the team has a clear, centralized view of return abuse.

• Stronger executive confidence and “psychological wins.” Leadership finally sees fraudsters attempting $10K returns and concrete wins against bad actors who had been taking advantage of the brand.

Fatty15 needed a solution that could identify fraudulent orders when the order was placed, before they shipped, while still allowing legitimate customers to check out smoothly.

Wyllo delivered on both fronts.

Fraud blocked at first purchase

Before Wyllo, the team often didn’t detect fraud until after a second order or refill. Wyllo helps Fatty15 stop fraud earlier in the customer lifecycle, instead of waiting for refills or repeat orders to reveal risky patterns. Dennis highlights, “Before Wyllo, we’d sometimes let the first order go out and only catch issues later through Shopify flows. Since implementing Wyllo, it has transformed our ability to catch fraud at the first purchase, without having to wait for refills or a day-two order.”

Instead of reacting after fulfillment, fatty15 now proactively stops fraudulent orders before they enter the fulfillment pipeline.

Reduced investigation volume without blocking real customers

With more accurate risk decisions, fatty15 spends less time chasing down orders that are actually safe and avoids letting review queues slow down growth. As a company in hypergrowth, that time back adds up fast, giving the team bandwidth to focus on scaling instead of second-guessing checkout.

Fewer chargebacks, better outcomes on the ones that remain

By catching more fraud upfront, fatty15 has fewer disputes overall, and the remaining chargebacks are easier to fight and win. “Fewer chargebacks and higher win percentage have definitely been a win-win for us,” says Dennis.

For a subscription first business like fatty15, fraud prevention is not just about stopping bad orders. It is about protecting the lifetime value of legitimate customers and ensuring marketing spend converts into real subscribers rather than fraudulent transactions. By improving order decision accuracy at checkout, fatty15 was able to approve more real customers while blocking fraud earlier, strengthening both revenue capture and long term customer economic
