About CartEngine Back in Stock Alerts for Woo…
From the official readme · v1.0.0Description
CartEngine Back in Stock Alerts for WooCommerce helps recover sales from out-of-stock products. Instead of losing customers forever, let them subscribe with one click and automatically email them when you restock.
No complicated setup. No bloat. Just a clean “Notify Me” form, reliable email delivery, and a simple subscriber dashboard right inside WooCommerce.
How It Works
- A visitor lands on an out-of-stock product page
- They enter their email and click “Notify Me When Available”
- You restock the product (manually or via import)
- The plugin automatically sends a back-in-stock email to all subscribers
- The customer clicks the link and completes their purchase
Key Features
Back-in-Stock Notifications
Automatically triggered when product stock status changes to “in stock” — no manual work needed. Emails are sent in batches of 50 with configurable throttle to protect your server.
AJAX Subscription Form
The “Notify Me” form submits without a page reload. Displays directly on the product page — no extra pages, no popups, no friction.
Variable Product Support
Customers can subscribe to specific variations (size, color, etc.). When you restock a particular variation, only subscribers to that variation receive the notification.
Shortcode [safw_stock_alert]
Place the subscription form anywhere using the [safw_stock_alert] shortcode. Supports product_id and variation_id attributes for full flexibility.
Subscriber Management
View and manage all subscribers from WooCommerce → Stock Alert Subscribers. Filter by status (active, notified, unsubscribed), sort by date or email.
Spam & Abuse Protection
Built-in IP-based rate limiting (5 subscriptions per IP per hour) keeps your list clean without any configuration.
Unsubscribe Link in Every Email
Every notification email includes a one-click unsubscribe link. No account required. GDPR-friendly by design.
Customizable Email & Form
Configure button text, form label, email subject, sender name, and accent color directly in WooCommerce → Settings → Stock Alerts.
Social Proof Counter
Optionally show how many people are waiting for a product (“12 people are waiting for this item”). Creates urgency and encourages subscriptions.
GDPR & Privacy Ready
Integrates with WordPress’s built-in Personal Data Export and Erase tools. Subscriber data stays on your server — no third-party services.

Frequently asked questions
Does it work with variable products?
Yes. When a customer selects an out-of-stock variation, the subscription form appears for that specific variation. When you restock that variation, only its subscribers receive the notification.
Will it slow down my store?
No. The plugin adds minimal overhead. The subscription form is loaded via AJAX, and notification emails are sent via WP-Cron in batches — not on page load.
Does it work with block themes like Twenty Twenty-Five?
Yes, fully compatible with block themes and classic themes. The form output is plain HTML with minimal inline styles.
How are emails sent — via my host or a third-party service?
Emails are sent via WordPress’s built-in wp_mail() function, which uses your hosting’s mail server by default. You can route through any SMTP plugin (WP Mail SMTP, FluentSMTP, etc.) for better deliverability.
Is it GDPR compliant?
Yes. Every notification email contains a one-click unsubscribe link. The plugin also integrates with WordPress’s Personal Data Export and Erase tools (Tools → Export Personal Data / Erase Personal Data).
Where can I manage subscribers?
Go to WooCommerce → Stock Alert Subscribers to view, filter, and delete subscriber records.
Can I use it with a shortcode?
Yes. Use [safw_stock_alert] to embed the form anywhere. You can pass product_id and variation_id attributes to target a specific product.
What happens if the same email subscribes twice to the same product?
The subscriber receives a message that they are already on the waitlist. If they had previously unsubscribed or been notified, their subscription is automatically reactivated.
Is there a limit to the number of subscribers?
No limit. Subscriber data is stored in your WordPress database. Notifications are sent in batches of 50 with a configurable throttle interval.
Is there a Pro version?
Yes. Stock Alert Pro adds demand analytics dashboard, smart stock-limited notify (FIFO queue), popup/modal mode, multiple email templates, conversion tracking, CSV export, double opt-in, and admin digest emails. One-time purchase, no subscription.
