BackSoon: Back in Stock Alerts

BackSoon adds a "Notify me" button to your product pages when variants sell out. Shoppers can sign up through a quick popup form to receive back in stock alerts. When the item becomes available again, each customer gets one email with a direct link to the variant, sent from your store's name. All replies go to your store's contact email. The waitlist shows which sold-out variants customers are waiting for, helping you decide what to reorder. You can export this list as CSV for easy tracking. The button and popup can be styled to match your theme without any code editing. Customer signups are automatically added to your Shopify customers and tagged "backsoon-waitlist," but they won't be subscribed to marketing emails. This back in stock notification system helps you capture sales you might otherwise lose on out-of-stock products.
