Panth Low Stock Notification — Back-in-Stock Email 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.

Admin Dashboard

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.

Email Templates

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:

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

Cron Delivery

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:

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

Ensure your server cron is running:

bin/magento cron:run --group=panth_low_stock

Frontend — Hyva & Luma

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

Troubleshooting

Issue	Cause	Resolution
"Notify Me" form not visible	Product is in stock or module disabled	Confirm stock status and module config
Emails not being sent	Magento cron not running	Run `bin/magento cron:run --group=panth_low_stock`
Subscriptions not saving	Form key / cache issue	`bin/magento cache:flush`
Wrong template (Luma on Hyva)	`Panth_Core` not installed	`composer require mage2kishan/module-core`
Duplicate emails	SMTP retry collision	Enable "Retry Failed Sends" = No temporarily

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