Back in Stock Notifications for WooCommerce adds a Subscribe button to out-of-stock products. When a customer clicks it, a customisable modal form collects their email (and optionally their name). When the product is back in stock, the plugin sends them a personalised notification email automatically — or you can trigger it manually.

Supports simple and variable products.

Main Features

✔️ Subscribe button on out-of-stock product pages (simple & variable)

✔️ Send Test Email — preview any email template with real product data before sending to customers

✔️ Bulk export subscribers to CSV
✔️ Customisable button colours (background & text)

✔️ Duplicate subscription prevention
✔️ reCAPTCHA v2 to block spam subscriptions
✔️ HubSpot integration — auto-create or update contacts on every subscription

Subscription Form Preview

Click the Preview button on the Subscription Form settings page to open a dedicated preview page. It shows the exact Subscribe button (with your saved colours and text) on a clean canvas — click it to open the modal and inspect the layout, title, fields, and before/after text. Submission is disabled so it’s completely safe to test.

Send Test Email

Each email template (Confirmation and Back in Stock Notification) has a Send Test Email button. Click it to open a dedicated test page where you can:

Search for any product (or select a specific variation)
Enter any recipient email (pre-filled with your admin email)
Send the email immediately — merge tags are replaced with real product data

The subject is prefixed with [TEST] so you can distinguish it from live emails. Subscriber name tags ([wsnm-first-name], [wsnm-last-name]) are substituted with sample values (John / Doe).

Subscriptions

Each subscription stores:

First Name (optional)
Last Name (optional)
Email
Status (Waiting, Sent, Paused)
Product (Simple or Variable)

Duplicate subscriptions are prevented. If someone with the same email tries to subscribe to the same product again, a warning message is shown instead.

Subscriptions can be filtered by product, searched by email, and exported in CSV format from the WordPress admin.

Merge Tags

Use these tags in email subject lines and body content:

[wsnm-first-name] – Subscriber’s first name
[wsnm-last-name] – Subscriber’s last name
[wsnm-email] – Subscriber’s email address
[wsnm-product-title] – Product name (including variation name if applicable)
[wsnm-product-price] – Product price with currency symbol
[wsnm-product-quantity] – Available stock quantity, or “unlimited” if unmanaged
[wsnm-product-url] – Direct link to the product (variation pre-selected for variable products)

Integrations

reCAPTCHA v2

Add a “I’m not a robot” checkbox to the subscribe form to block automated spam submissions. Requires a free Google reCAPTCHA v2 account. Configure your Site Key and Secret Key under Settings Integrations.

HubSpot

Connect to your HubSpot account to automatically create or update a contact every time someone subscribes:

Each subscriber is created as a HubSpot contact (email, first name, last name)
If a contact with the same email already exists, it is found and reused — no duplicates
A note is attached to the contact with the name of the subscribed product
The sync result (contact link or error) is visible on each subscription’s detail page in the WordPress admin

To connect: go to Settings Integrations, enable HubSpot, paste your Private App token (requires the crm.objects.contacts.write scope), and click Check connection to verify.

Developer Filters

The plugin exposes the following filters:

wsnm-text-cta – Override the subscribe button text shown on the product page
wsnm-modal-title – Override the modal header text
wsnm-modal-form-button – Override the submit button text inside the modal
