How it sells itself

A form on sold-out product pages lets shoppers ask for one email when an item is back. Restocks are detected automatically, and stock is checked again moments before each alert goes out. Small restocks are sent in batches sized to the stock. See every sign-up and alert in a log, with a plain reason when one was not sent. Edit the email, preview it, send yourself a test, and export or import your waiting list as CSV.

Every sold-out product page is a sale that walked away. Waitly catches those shoppers: when a variant hits zero, a small form appears on your product page, and the moment you restock, everyone waiting gets an e-mail with a link to the product. You write the sender name, subject and message yourself. Your dashboard shows who is waiting and which products are most in demand, so you know what to reorder.

Key points
  • A Notify me form on sold-out products, with no theme code to edit
  • Stock is checked again moments before each alert is sent
  • See every alert, and the plain reason when one was not sent
  • Edit the alert email, preview it and send yourself a test
  • Sign-up form appears on sold-out variants and hides when back in stock
  • Automatic e-mail with a direct product link the moment stock returns
  • Dashboard with your waiting list and the products most in demand
  • Your own sender name, subject and message, in Dutch or English
