Magento 2 Back-in-Stock Notifications Extension

Toweringmedia Backorder (toweringmedia/module-backorder) equips Magento 2.4 stores with a purpose-built back-in-stock notification workflow. When a product is not salable, shoppers can subscribe directly from the product page; when salability returns, the extension automatically delivers the alerts you configure.

Email notifications use configurable Magento templates so you can match your brand voice, while optional Twilio SMS adds higher-signal restock messaging for customers who opt in with a phone number.

Highlights

• Subscribe block wired into native Luma and Hyvä catalog product layouts
• Persistent subscription records tied to products (and store context) for reliable delivery
• Cron-driven processing that watches for salability changes and dispatches pending notifications
• Admin tools for sender identity, template selection, SMS credentials, and test messaging
• Compatible with Magento 2.4.x Open Source and Adobe Commerce

Recommended rollout

Validate in a staging environment first: place test subscriptions across simple/configurable scenarios, simulate replenishment, and confirm both email and SMS paths before enabling in production.
