Low Stock & Back-in-Stock Alerts for Magento 2

Never lose an out-of-stock sale again. Let customers subscribe for back-in-stock email alerts directly from the product page, manage every subscription from a powerful admin dashboard, send notifications automatically via cron, place the "Notify Me" button exactly where you want it, and customize the email template to match your brand — fully compatible with both Hyva and Luma themes.

Panth Low Stock Notification turns every "Out of Stock" product page into a future sale. When a product is unavailable, a Notify Me When Available form appears so shoppers (guest or logged-in) can submit their email and get notified automatically the moment the product is restocked. Store admins get a dedicated subscription dashboard to view, filter, export, and manually trigger alerts. A built-in cron job watches stock-status changes and dispatches branded email notifications using a fully customizable email template — no manual work required.

The extension supports configurable button placement (before/after add-to-cart, custom container), works seamlessly with simple, configurable, bundle, and grouped products, and ships with production-ready templates for both Hyva (Alpine.js + Tailwind) and Luma (Knockout + LESS) storefronts. MEQP-compliant, translation-ready, and built on the Panth Core foundation.

General

Button / Form Placement

Email

Cron

Navigate to Panth Infotech → Low Stock Notification → Subscriptions.

You'll find:

• Full subscriptions grid — Product SKU, email, customer name, store, status (Pending / Sent / Cancelled), created date
• Bulk actions — Delete, Mark as Sent, Resend Email
• Row actions — View details, Send Now, Cancel
• Filters — by product, email, store, status, date range
• Exports — CSV / XML via the standard Magento export button

A waiting customers widget can also be added to any dashboard page that shows top out-of-stock products sorted by number of subscribers — perfect for prioritising restocks.

The module ships with a default transactional email template:

• Identifier: panth_lowstock_notification_template
• Location: view/frontend/email/notification.html
• Variables available:
• {{var product.name}}
• {{var product.url}}
• {{var product.image}}
• {{var product.price}}
• {{var customer.name}}
• {{var store.name}}
• {{var unsubscribe_url}}

To customize:

1. Go to Marketing → Communications → Email Templates
2. Click Add New Template
3. Load default template Panth Low Stock Notification — Default
4. Edit HTML / text content
5. Save and assign it in the module configuration

Panth Low Stock Notification registers a cron group:

<group id="panth_low_stock">
 <job name="panth_low_stock_notify" instance="Panth\LowStockNotification\Cron\SendNotifications" method="execute">
 <schedule>*/5 * * * *</schedule>
 </job>
</group>

On every run, the cron:

1. Queries products that have transitioned from out-of-stock → in-stock since the last check
2. Loads matching Pending subscriptions in batches
3. Dispatches each email via the configured template & sender
4. Marks subscriptions as Sent (or Failed for retry)
5. Writes an entry to var/log/panth_low_stock.log

Ensure your server cron is running:

bin/magento cron:run --group=panth_low_stock

The correct template is auto-selected by Panth_Core's theme detection:

• Hyva: view/frontend/templates/product/notify.phtml — Alpine.js form, Tailwind classes, no RequireJS
• Luma: view/frontend/templates/product/notify.phtml — Knockout/jQuery form, responsive LESS styles

Both templates:

• Show only when the product is out of stock
• Pre-fill the email field for logged-in customers
• Submit via AJAX to /panth_lowstock/subscribe/save
• Display success / error messages inline
• Are fully translatable

Enable Debug Mode in Panth Core settings to see detailed logs at var/log/panth_low_stock.log.
