# "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 &quot;Notify me&quot; 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="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.*

<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 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
