Improve your marketing and customer service with Jigoshop Product Changes Notification, which automatically updates your customers when changes occur to a product. Rather than remembering to contact every customer when a product price or availability changes, this extension will take care of it for you – alerting anyone who was subscribed to be notified when a change occurs. For example, make sure anyone interested knows when a product is back in stock. You can decide exactly when customers should be informed, for example, when there is a price change, or only if the new price is lower. And you can customize the content of the email using text and images.
