Back in stock notifications for WooCommerce

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) ✔️ Subscribe button on shop & listing pages — appears on product tiles in shop, category, search, and related product sections ✔️ Button Visibility control — show on both, single product page only, shop/listing pages only, or disable entirely ✔️ Customisable modal form — title, button text, before/after text ✔️ Live form preview — see the button and modal exactly as customers will, before going live ✔️ Personalised confirmation and back-in-stock notification emails ✔️ Send Test Email — preview any email template with real product data before sending to customers ✔️ Default email templates included (ready to use out of the box) ✔️ Merge tags for dynamic content (name, email, product title, price, URL, quantity) ✔️ Automatically mode — notifications sent when WooCommerce stock status changes ✔️ Manually mode — trigger notifications from the product page when you're ready ✔️ Pause notifications for specific products ✔️ Filter and search subscriptions by product or email ✔️ Bulk export subscribers to CSV ✔️ Customisable button colours (background & text) ✔️ First & Last Name fields (optional — enable or disable per your preference) ✔️ 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

External Services This plugin optionally connects to the following third-party services. These connections are only made when you explicitly enable the corresponding integration in Settings → Integrations. Google reCAPTCHA v2 (optional) Used to verify that subscription form submissions are made by a human. When enabled, the reCAPTCHA script is loaded from Google's servers and the form response is verified against Google's API.

• Service: Google reCAPTCHA
• Data sent: user's reCAPTCHA response token and IP address
• Privacy Policy: https://policies.google.com/privacy
• Terms of Service: https://policies.google.com/terms

HubSpot (optional) Used to automatically create or update a CRM contact when someone subscribes. Subscriber name, email, and the subscribed product name are sent to HubSpot.

• Service: HubSpot CRM API
• Data sent: subscriber email address, first name, last name, subscribed product name
