Meet the KWI
Klaviyo Connector
The KWI Klaviyo Connector syncs your customer profiles and omnichannel sales data from KWI into Klaviyo. In-store and online purchases are tied to the same customer profile, giving your marketing team a complete view of purchase behavior across every channel. The result is smarter segmentation, more relevant campaigns, and marketing that reflects how your customers actually shop.

What It Looks Like
When It Works
John Varvatos had excess inventory in larger-size Henley sweaters heading into a key holiday weekend. Rather than running a broad promotion, they used the KWI Klaviyo Connector to identify customers with a history of buying similar products and timed the campaign around an incoming storm.
Result: 23% increase in sales of that sweater style. Clean sell-through. No wide discounting.
Built on the same platform that runs your store
The KWI Klaviyo Connector is part of KWI’s unified commerce platform, the same infrastructure powering POS, Omnichannel Order Management, and Merchandising for multi-location specialty retailers. Most marketing integrations pull from one channel. This one pulls from your entire operation.
KWI has been the operational foundation for specialty retail for 40+ years.
