Restock Notifications: Keep Demand Warm When Products Are Sold Out

2026-03-21

Restock Notifications helps you capture customer demand when products are out of stock and gives you a way to follow up when inventory returns.

What It Does

  • Lets shoppers submit their email for restock alerts when they encounter out-of-stock variants through the Product Search Widget or product recommendation cards
  • Automatically saves every request for later review
  • Stores details such as product, variant, email, and submission time
  • Supports filtering by product, variant, and date range

Why It Matters

  • Keeps customer interest alive during out-of-stock moments
  • Helps you understand which products and variants have the strongest demand
  • Gives you a more targeted way to follow up once inventory is back
  • Reduces potential revenue loss caused by temporary stockouts

How to Enable It

  • Enable the Product Search Widget under Widget Settings > Feature Widgets
  • Or enable product recommendation cards under Advanced Settings > Product Recommendation
  • You can also add the HeiChat Restock Alert block to product pages in the Shopify Theme Editor

Once enabled, shoppers will see the restock notification option on out-of-stock variants.
