Prelude ‑ Waitlist & Demand

Prelude – Waitlist & Demand is positioned as a lightweight waitlist tool for sold-out and coming-soon products that helps merchants capture demand before restocking. The app lets shoppers choose an exact variant and submit an email without creating an account or making a payment, then organizes signups in Shopify admin by vendor, product, and variant so merchants can see what to reorder and in what quantity. It also includes daily email summaries, filtering, CSV export for suppliers, theme matching, and automatic data removal on uninstall.
