Yulebox ‑ AI Advent Calendar

Yulebox is a focused Shopify app for creating branded advent and Christmas calendars that can be customized with uploaded artwork, AI-generated designs, or ready-made themes. It helps merchants drive repeat visits through the holiday season by requiring shoppers to sign up with email to open daily doors, while also issuing each shopper a single-use Shopify discount code to reduce coupon sharing. The app also lets merchants set up and test the full calendar on their store before launching, making it straightforward to preview the experience and match it to their brand.
