135% Increase in Klaviyo Attributed Revenue Through Deliverability & Segmentation Optimization for Premium Wellness Brand

Despite having a valuable subscriber base and strong products, SōKO’s email marketing program faced limitations that prevented it from reaching its full potential. List quality issues and a large population of disengaged contacts were impacting deliverability and suppressing inbox placement. Campaigns lacked the advanced audience segmentation needed to consistently engage subscribers based on recent activity and intent. As a result, engagement rates, conversions, and revenue opportunities were being left on the table.

SmartSites focused on optimizing the foundation of SōKO’s email marketing program before introducing any major changes. Our team conducted extensive list hygiene initiatives to remove disengaged contacts, strengthen sender reputation, and improve inbox placement. We implemented advanced engagement-based segmentation strategies centered around 30, 60, and 90-day subscriber activity windows, allowing campaigns to reach the audiences most likely to engage and convert. Campaign execution was further refined through stronger creative direction, more compelling subject lines, and optimized send timing strategies designed to increase visibility and interaction. Rather than relying on new product launches or aggressive discounting, SmartSites unlocked growth by improving how existing campaigns were delivered, targeted, and experienced by subscribers.
