By enabling consumers to sign up for stock updates concerning out-of-stock products with Magento 2 out of stock notification, you can gather leads and turn them into sales. The extension enables a subscription option, allowing you to gauge consumer demand and interest in a product and make it available in accordance with those findings. As you restock the stock, the subscribers automatically receive an email update. You can substitute the "Add to Cart" option with the "Subscribe" option for the benefit of your consumers. If a user expresses interest in these products, you, as the store administrator, will also receive email updates.
When a product becomes out of stock, you no longer have to hide it. This is made possible by the Magento 2 out of stock notice extension. To notify users as soon as the product is available, you can instead enable a subscription option on the product pages. As a result, it keeps potential buyers from leaving because the product is unavailable.
