Magento 2 Stock Notification handles bulk alerts by sending update emails when products return to stock. Store admins can notify many subscribed customers at the same time. The system groups requests and processes them in batches. This avoids server load issues. Customers receive alerts only for products they follow. Admins can manage queues from the backend easily. With Webkul's Magento 2 Stock Notification, alerts are sent in an organised way. This helps stores save time and keeps customers informed without delays or confusion during high demand periods.
