The extension allows you to notify customers when products become available again using manual, automatic, or individual selection methods.
1. Manual Notification
To manually send notifications, click the Check Products & Notify button.
The extension will review all alert records and verify product availability based on the stock validation rules configured in the extension settings.
Customers whose requested products are now available will receive:
- Email notification
- SMS notification (if SMS integration is enabled)
This option is useful when you want to manually control when notifications are sent, for example after updating product quantities or restocking inventory.

2. Automatic Notification (Cron Job)
You can fully automate the notification process using a cron job.
The extension provides a cron command in the settings page. Add this command to your hosting control panel cron scheduler (such as cPanel or server cron manager).
You can configure the cron job to run:
- once per day
- multiple times per day
- based on your inventory update frequency
When the cron job runs, the extension automatically:
- checks product availability
- validates alerts based on configured rules
- sends notifications to eligible customers
Note:
Cron command format may vary depending on server configuration. The command provided in the settings works in most environments. If it does not work on your server, your hosting provider can help configure the correct cron format.

3. Notify Selected Customers (Individual Notification)
You can also send notifications to specific customers manually.
Steps:
- Go to the Alerts tab
- Select the alert records you want to notify
- Click Selective Operation
- Click Notify Selected
This method sends notifications only to the selected records.
Important:
In this method, stock availability is not validated. Notifications are sent regardless of product quantity or stock status.
This option is useful when:
- You want to inform customers about alternative availability situations
- You want to notify customers manually
- You want to send early notifications
- You want to handle special cases individually
