About Under 5’10
Under 5'10 is a men’s fashion brand focused on delivering clothing that fits shorter men perfectly, right off the rack. Their collection includes expertly designed jeans for short men, pants for short men, and a variety of tops tailored for shorter frames. By prioritizing fit and proportion, Under 5'10 helps men under five foot ten look and feel their best without the hassle of alterations.
Rising CAC demands new growth channels
Like many consumer brands, Under 5’10 relied heavily on paid social ads to drive growth. But competition and ad costs on platforms like Meta continued to increase, driving up acquisition costs. This was particularly problematic for one-time shoppers. Under 5’10 set out to solve this with retention campaigns sent through Klaviyo — but they didn’t see much success winning customers back with their bulk email flows.
Retention emails that fit as well as their clothes
Under 5'10 needed a more tailored and effective approach to drive revenue through repeat orders. They partnered with Remarkable AI to launch a win back flow with 1:1 emails that got customers’ attention — and got them shopping again.
- Seamless integrations for rich context: One-click integrations with existing systems — like Gorgias, Shopify, and Klaviyo — provide the data Remarkable AI uses to create personalized emails that land in the recipient’s primary inbox and look individually sent.
- Identify high-potential shoppers: With context from customer conversations in Gorgias, order history in Shopify, and browsing history in Klaviyo, Remarkable AI identified the lapsed Under 5’10 customers most likely to purchase again.
- Generate messages for audience of 1: Remarkable AI treats each recipient as an individual audience. Email copy. Image. Personalized cart. Promo code. Every detail in each message generated reflects that recipient’s profile, purchase history, and preferences.
- Done-for-you campaigns: Under 5’10 needed a solution that would reduce their workload, not add to it. With Remarkable AI, all they needed to do was sign off on the winback email strategy designed to support their goals. Remarkable AI does the rest.
Result: Customers come back to shop
The 1:1 retention emails quickly became the top performing winback flow. Within the first month, the winback emails from Remarkable AI drove more than $20,000 of revenue.
- 15.3% conversion rate
- $20.43 revenue per recipient
- 20X return on spend
- $20,000+ in revenue in Month 1 alone
