Go beyond the basics with the Klaviyo marketing app. New stores get a guided setup — sign-up form, welcome email, and abandoned-checkout flow — without leaving Shopify Admin. Unify data from 350+ integrations and boost marketing performance with campaigns, smart segmentation, and automated workflows from Klaviyo’s AI Agents. Over 117k brands use Klaviyo and Shopify to grow faster with personalized emails, SMS, WhatsApp messages, and marketing automation tools that turn browsers into buyers.

WooHoo helps Shopify stores grow email and SMS subscribers with popups and signup forms. Build and customize every popup in a no-code drag-and-drop editor, starting from a growing template library. Create email capture popups, spin-to-win discount wheels, newsletter signups, and exit-intent coupon offers, then target them by page, device, and behavior. Send email campaigns or sync contacts to your email tools, and track signups, orders, and revenue from one dashboard.
