Beltoft In-Stock Notifier for WooCommerce adds a subscription form to out-of-stock products so customers can leave their email and get notified when the product is restocked. Emails are sent using WooCommerce's email template so they match your store's design.<\/p>\n\n

Key Features<\/h3>\n\n
    \n
  1. Subscription form on out-of-stock products \u2014 works with simple, variable, grouped, and external products.<\/li>\n
  2. Variable products: form shows\/hides automatically when selecting out-of-stock variations.<\/li>\n
  3. Notifications sent via WooCommerce email templates \u2014 same look as your order emails.<\/li>\n
  4. Email settings (subject, heading, on\/off) under WooCommerce > Settings > Emails.<\/li>\n
  5. Batch sending via Action Scheduler \u2014 handles thousands of subscribers without slowing down.<\/li>\n
  6. Detects stock changes from admin, REST API, CLI, and ERP systems.<\/li>\n
  7. Admin dashboard with stats and a manual \"Send Notifications\" button per product.<\/li>\n
  8. Subscription list with search, filters, pagination, and bulk actions.<\/li>\n
  9. One-click unsubscribe link in every email.<\/li>\n
  10. Optional GDPR checkbox, honeypot spam protection, and rate limiting.<\/li>\n
  11. Shortcode [bisn_form]<\/code> for custom placement.<\/li>\n
  12. Activity logging via WooCommerce logger.<\/li>\n<\/ol>\n\n

    How It Works<\/h3>\n\n
      \n
    1. Customer visits an out-of-stock product and enters their email.<\/li>\n
    2. When the product comes back in stock, the plugin picks it up via WooCommerce hooks.<\/li>\n
    3. Emails are queued and sent in batches \u2014 each one includes the product image, a \"Shop Now\" button, and an unsubscribe link.<\/li>\n
    4. Custom hook available for CDN\/Varnish cache purging if needed.<\/li>\n<\/ol>\n\n

      Configuration<\/h3>\n\n

      Form Placement<\/h3>\n\n
        \n
      • The form shows automatically on out-of-stock product pages.<\/li>\n
      • To place it yourself, disable auto-placement in settings and use [bisn_form]<\/code> or [bisn_form product_id=\"123\"]<\/code>.<\/li>\n<\/ul>\n\n

        Email Template<\/h3>\n\n
          \n
        • Uses WooCommerce's email system \u2014 same header, footer, and colours as your other store emails.<\/li>\n
        • Customise subject, heading, body text, button text, and footer text under WooCommerce > Settings > Emails > Back In Stock.<\/li>\n
        • Use {product_name}<\/code> and {site_title}<\/code> placeholders in any of these fields.<\/li>\n
        • Override the template by copying templates\/emails\/back-in-stock.php<\/code> to your theme's woocommerce\/emails\/<\/code> folder for more complex customisations.<\/li>\n<\/ul>\n\n

          Batch Sending<\/h3>\n\n
            \n
          • Configurable batch size (default 50) and throttle between emails.<\/li>\n
          • If there are more subscribers than one batch, the next batch runs 60 seconds later.<\/li>\n
          • For low-traffic sites, set up a real system cron for reliable scheduling.<\/li>\n<\/ul>\n\n

            Hooks & Filters<\/h3>\n\n

            Developers can extend the plugin:<\/p>\n\n

              \n
            • bisn_form_html<\/code> \/ bisn_form_fields<\/code> \/ bisn_form_heading_text<\/code><\/li>\n
            • bisn_before_subscription<\/code> \/ bisn_after_subscription<\/code><\/li>\n
            • bisn_validate_subscription<\/code><\/li>\n
            • bisn_before_notification_sent<\/code> \/ bisn_after_notification_sent<\/code> \/ bisn_after_batch_sent<\/code><\/li>\n
            • bisn_stock_status_triggers<\/code> \u2014 customise which statuses trigger notifications (default: instock, onbackorder)<\/li>\n
            • bisn_cache_purge_product<\/code> \u2014 fire custom cache purge logic (e.g. Varnish, CDN)<\/li>\n<\/ul>\n\n\n
                \n
              1. Upload the beltoft-in-stock-notifier<\/code> folder to \/wp-content\/plugins\/<\/code> or install via the Plugins screen.<\/li>\n
              2. Activate the plugin.<\/li>\n
              3. Go to WooCommerce > In-Stock Notifier<\/strong> to configure.<\/li>\n
              4. Optionally adjust the email text under WooCommerce > Settings > Emails > Back In Stock<\/strong> (body text, button text, footer text).<\/li>\n<\/ol>\n\n\n
                \n

                Does it work with variable products?<\/h3><\/dt>\n

                Yes. The form appears when a customer selects an out-of-stock variation. The specific variation is tracked so the notification only sends when that variation is back.<\/p><\/dd>\n

                Does it pick up stock changes from the REST API or ERPs?<\/h3><\/dt>\n

                Yes. It hooks into WooCommerce's core stock events which fire regardless of how stock is updated.<\/p><\/dd>\n

                Which email providers does it work with?<\/h3><\/dt>\n

                Any. It sends through WooCommerce's email system which uses wp_mail()<\/code> \u2014 works with SMTP plugins, Amazon SES, SendGrid, etc.<\/p><\/dd>\n

                Do emails match my store's design?<\/h3><\/dt>\n

                Yes. They use WooCommerce's email template \u2014 same header, footer, and styling as order emails.<\/p><\/dd>\n

                Can I send notifications manually?<\/h3><\/dt>\n

                Yes. The Dashboard tab has a \"Send Notifications\" button next to each product.<\/p><\/dd>\n

                How do customers unsubscribe?<\/h3><\/dt>\n

                Every email has a one-click unsubscribe link. No login needed.<\/p><\/dd>\n

                What if the product sells out again before all emails go out?<\/h3><\/dt>\n

                The sender checks stock before each batch. If the product is out of stock again, remaining emails are skipped.<\/p><\/dd>\n

                Does it handle cached pages?<\/h3><\/dt>\n

                WooCommerce and popular caching plugins already purge product pages when stock changes. The plugin also fires an bisn_cache_purge_product<\/code> hook if you need custom purge logic (e.g. Varnish or a CDN).<\/p><\/dd>\n\n<\/dl>\n\n\n
