Turn sold-out products into sales with notify me buttons and automatic back in stock email alerts.
Backly adds a notify me button to sold-out products so shoppers join a waitlist instead of leaving. When you restock, everyone waiting gets an automatic back in stock email with a direct link to buy. The widget matches your theme, supports every variant, and follows inventory across locations, no code needed. See which sold-out products shoppers want most, track clicks, sync signups to Klaviyo, and export your waitlist any time. Enable the app embed and you are live in minutes.
- Notify me button appears on sold-out products, no code or theme edits
- Back in stock emails send the moment inventory returns, at any location
