# Setup

To enable the notifications, you have to go to `Extensions > My Extensions > Apps` in the admin. and then at the app "Back in stock notification" right click on `... > Configuration` on the right.

Now you are in the settings for the app. You now have to perform the following two steps:

* First, you have to activate the app for your sales channels via the checkbox `Activate`.
* Choose how emails should be sent — see [Email delivery](/shopware/extensions/back-in-stock-notification-cloud/email-template.md). The recommended path uses Shopware's own mailer and lets you edit the email template in the admin. No SMTP credentials are required.

Finally, you need to press the `Save` button. That was all!

{% hint style="warning" %}
**Attention**

The entry of the email addresses in the product detail pages is only visible if the associated product is not available. Usually this means that the `Stock` is set to `0` and the `Clearance sale` is set to `on`. However, this can differ slightly per store, as other extensions can also have an influence on the availability.
{% endhint %}

{% hint style="info" %}
**Tip**

Emails to customers are only sent when a product that was previously unavailable (e.g. due to lack of stock), now becomes available again. It is exactly at this transition that the delivery happens.
{% endhint %}
