eShoopy Back in Stock adds a Notify me button to sold-out products and variants. Shoppers subscribe in one tap and are emailed automatically when you restock, driven by real-time inventory webhooks. Waiting lists are tracked per variant, and notification emails carry your logo, product photo and a buy button, sent through the app's built-in email service or your own SMTP. Includes double opt-in, a customer-account waitlist, demand insights, CSV export and GDPR privacy webhooks.

• Notify me button on every sold-out product and variant captures lost demand
• Automatic restock emails the instant inventory is back above zero
• Demand insights show what shoppers wait for, so you reorder the right stock
