Case Study: Waves Gear achieves an 8% revenue lift with Klaviyo

How Product Reviews Helped Waves Gear Get an 8% Revenue Lift

Waves Gear makes floatable sunglasses (and beach micro towels) to solve the problem of eyewear that sinks, selling primarily through a Shopify store. As paid channels like Facebook yielded declining ROI, the team needed a scalable way to capture customers, drive repeat purchases, and improve site conversion and SEO — starting with recovering and growing their email list.

They implemented Klaviyo-powered email tactics: a homepage pop-up offering $10 off that generated 2,000+ signups, plus a 7-day post-purchase autoresponder that offers a $20 gift card in exchange for a product review. Reviews boosted on-site content and conversions; 34% of reviewers returned to buy again, and the autoresponder produced a 7.8% revenue lift. Testing also showed dollar-off offers outperformed percentage discounts, reinforcing email as their most profitable channel.
