WPC Back In Stock Notifications for WooCommerce

WPC Back In Stock Notifications helps you never miss a potential customer when a product is out of stock. This plugin allows customers to subscribe for email notifications as soon as the items they interest in are back in stock.

With a modern interface, powerful features, and high customizability, it is the optimal solution for customer retention and conversion rate optimization for your WooCommerce store.

Detailed Features

• Automatic Form Visibility: Automatically detects out-of-stock products and displays the “Notify Me” subscription form.
• Variable Product Support: The form dynamically appears or disappears based on whether the customer selects an in-stock or out-of-stock variation.
• Flexible Shortcode: Use `[wpcbs_form]` to place the subscription form anywhere on your website (Sidebar, within post content, custom pages, etc.).
• Visual Reports & Statistics: In-depth statistics page with charts (Chart.js), allowing you to track subscription trends over time and identify most popular products.
• Subscriber List Management: A centralized management interface for Admins to view, search, and filter the list of customers waiting for notifications.
• My Account Integration: Customers can view and manage all their subscribed products directly in the “Waitlist Notifications” tab on their “My Account” page.
• Smart Blacklist System: Block unwanted emails or IP ranges using wildcards (*). e.g., `*@bad-domain.com` or `123.45.*`.
• Minimum Stock Threshold: Only send notifications when the new stock reaches a certain level (e.g., only notify when at least 5 items are available).
• Customizable Content: Easily change form titles, button labels, success messages, and notification email templates.

Deep Dive into Tracking Feature

The tracking system of WPC Back In Stock Notifications is designed to provide store owners with a comprehensive view of customer demand:

• Detailed Data Storage: Each subscription is recorded with full information: Email, Product/Variation ID, user ID (if logged in), IP address, and precise timestamp.
• Status Lifecycle Management: The plugin tracks the lifecycle of a request from `pending` (waiting), `notified` (notification sent), to `unsubscribed` (cancelled). This tells you exactly how many customers are genuinely interested in each product.
• Engagement Tracking: A standout feature. When a customer receives an email and clicks the link to view the product, the system automatically records the `clicked_at` time. You can use this data to measure the effectiveness of your notification campaigns.
• Absolute Security: All tracking and unsubscribe links are protected by a unique hash (MD5 combined with WordPress salt), ensuring no unauthorized access to other people’s data.

Deep Dive into AJAX for Tasks

The plugin maximizes AJAX technology to ensure a seamless user experience and peak system performance:

• No-Reload Subscription: Customers just enter their email and click the button; all validation processes (blacklist check, IP check, database saving) happen in the background. Success messages appear instantly without the customer losing track of the product they are viewing.
• Smooth My Account Management: Unsubscribing from a product in the “My Account” page is performed via AJAX. The list updates its status automatically without requiring a page reload.
• Flexible Admin Tasks: In the Admin management area, actions such as manually unsubscribing a customer are performed lightning-fast via AJAX, helping administrators manage thousands of records efficiently.
• Background Processing via Action Scheduler: To avoid slowing down the website when thousands of customers subscribe to a single product, the plugin integrates with Action Scheduler. When a product is back in stock, instead of sending all emails at once (which could crash the server), the plugin creates asynchronous tasks to process them gradually in the background.
