# Boomerang’s Out of stock reminder

**Conversion rate**

**Signup rate**

**Challenge**
Capturing demand from out-of-stock products.

**How they did it**
Instead of having people leaving the site when they see that a product is out of stock, Boomerang created a campaign in Triggerbee that was triggered when you clicked a link with the text “Size not available?”.

When a product size is back in stock, they send a reminder to the people who asked for a notification.

This helps Boomerang both with collecting email addresses, to build an email list, and enriching their email database and target audience with clothing size information.

They used one campaign to show a popup for visitors who clicked on a link on product pages, when certain sizes were out of stock.
