PopupBoost is a Shopify-focused marketing app that helps merchants turn store visitors into subscribers and customers through interactive, gamified popups. Its offerings include customizable spin wheels, scratch cards, and other popup campaigns designed to encourage email signups and promote discounts. Merchants can tailor colors, fonts, labels, images, animations, timing, and placement to match their brand, and choose triggers such as exit intent, scroll depth, time on page, or cart value.

The app captures customer emails before a game, can also collect phone numbers, and automatically generates Shopify discount codes for prizes. Winning codes are displayed to customers, sent by email, and can apply at checkout. A real-time analytics dashboard tracks spins, conversions, and signups, while a live activity feed shows subscriber and prize activity. PopupBoost integrates with existing Shopify themes and states that its asynchronously loaded script is designed to avoid affecting page speed. The service is advertised as free, with unlimited campaigns and multiple game types; its FAQ specifies 500 monthly impressions on the Free plan.
