How it sells itself

Restock Alerts captures emails from shoppers on sold-out product pages, then automatically notifies them when inventory returns, turning missed sales into recovered revenue. Shoppers get back in stock alerts and click to buy instantly. Merchants get a subscriber dashboard with stats, product breakdowns, and CSV/JSON export, plus customizable email templates and automatic or manual send modes.

RestockBolt captures shopper interest on sold-out variants and emails them the moment inventory returns. Notifications link to a pre-filled Shopify checkout, so shoppers can buy in one click instead of being sent back to the product page! Per-variant waitlists make sure shoppers are only notified when the exact size or option they want is restocked.

Key points
  • Emails subscribers automatically the moment inventory is back in stock.
  • Track signups per product and export the full list as CSV or JSON.
  • Edit sender name, subject, and body to match your brand; test before going live.
  • One-click checkout from every restock email, no trip back to the product page!
  • Waitlists are specific to variants - specific to exactly what shoppers want!
  • See exactly which sold-out products to restock first, ranked by demand!
  • Shoppers can sign up on category pages or product pages!
