# How are Back-in-stock subscriptions and Subscribers list different?

The Back-in-stock alerts in FoxKit app offers instant notifications for shoppers when items are available and ready for purchase again. :bell:

You can also utilize this feature to capture shoppers' purchase intent and build your email list.

## Back-in-stock subscriptions

**Back-in-stock subscriptions are customers who sign up for the back-in-stock (BIS) form** shown on your out-of-stock products.

Data collected via the BIS form can be saved in your Shopify customers list and/ or FoxKit subscriptions list.

&#x20;To find this setting, go to [**Back-in-stock** > **Form settings**](/foxkit-app/upsells/back-in-stock-alerts.md#form-settings).

{% hint style="warning" %}
If you activate email notifications for BIS (emails to be sent automatically when the product is re-stocked), **data collection to be saved in FoxKit subscriptions list is required**.

## FoxKit Subscribers list

Data of customers who **subscribe to your newsletter** ✉️ will be stored in FoxKit > **Subscribers**.

You will also find subscribers of FoxKit's [Pop-up](/foxkit-app/sales-boosting/pop-up.md) and [Lucky wheel](/foxkit-app/sales-boosting/lucky-wheel.md) there (if the feature's data collection is set as FoxKit subscribers list :white\_check\_mark:) .
