# "Notify me" widget: FAQs

Quick answers to the most common questions about how the **"Notify me" widget** works in XFlow.

<Expandable title="Why doesn’t the &#x22;Notify me&#x22; button appear on my product page?">
  This usually happens for one of these reasons:

  * **XFlow Helper** is not enabled in your theme
  * The product or variant is **not actually out of stock**
  * The product is **included in an active campaign**. *Learn more about* [*Campaigns*](https://docs.foxecom.com/xflow-app/campaigns/create-and-launch-a-restock-campaign)
  * Your theme uses a **custom product form** that doesn’t support auto-replacement
</Expandable>

<Expandable title="How do I turn the floating &#x22;Notify me&#x22; button on or off?">
  The floating button is controlled by a single setting in the app:

  1. From your XFlow dashboard, select "Notify me" widget settings
  2. In Back-in-stock settings, open the **Notify me button** tab
  3. Under **Button position**, turn the **Floating button** option off (turn it on to show it again)
  4. Click Save.

  The change applies to your live storefront. Refresh your product page to confirm.

  The "Notify me when available" button inside the product form stays exactly where it is (if enabled). Subscribers keep coming in, and your campaigns and workflows are unaffected.

<Expandable title="What's the difference between the inline button and the floating button?">
  Both let shoppers subscribe to a back-in-stock alert. They differ only in where they appear.

  * **Inline button**: sits inside the product form, replacing your theme's Add to cart / Buy now buttons. Does not follow the shopper when scrolling.
  * **Floating button**: a fixed tab pinned to the side of the screen that stays visible while scrolling.

  You control both under Back-in-stock settings > Notify me button > Button position.

<Expandable title="When is a back-in-stock email sent?">
  A back-in-stock email is sent when:

  * Inventory changes from **out of stock → in stock**
  * The product or variant becomes **fulfillable**
  * The related campaign or workflow is **active**

  <Hint type="warning">
    Emails are not sent just because inventory is added — the item must be *sellable.*
  </Hint>
</Expandable>

<Expandable title="Does the back-in-stock alert work for product variants?">
  Yes!

  * Customers can subscribe to **a specific variant**
  * Or choose to subscribe to **all variants** of a product

  How it works:

  * If a customer subscribes to a **specific variant**, they’ll be notified **only when that variant** is back in stock.
  * If they subscribe to **all variants**, they’ll be notified when **any variant** becomes available.
</Expandable>

<Expandable title="Will customers be notified only when a product is restocked in their own country?">
  Yes — **if location-based notifications are enabled**.

  When enabled:

  * Customers are notified only when the product is restocked at the **location/country they subscribed to.**

  When disabled:

  * All locations share the same back-in-stock alert.

<Expandable title="Is there a limit to how many back-in-stock emails can be sent?">
  No hard limits from XFlow.

  * Emails are sent based on actual restock events
  * Volume depends on your subscriber count and inventory changes.

  <Hint type="warning">
    Your email delivery may still be subject to your email provider’s limits.
  </Hint>
</Expandable>

<Expandable title="Can customers subscribe multiple times to the same product?">
  No.

  * XFlow prevents **duplicate subscriptions** for the same product or variant.
  * Once notified, the subscription is completed automatically.
</Expandable>

<Expandable title="Does the Notify me widget replace the Buy button?">
  Yes — by default.

  * When a product or variant is out of stock, XFlow automatically replaces:
    * Add to cart
    * Buy now
