Out-of-Stock & Back-in-Stock Notification for Magento 2

Key Features

Customer 'Notify me when available' subscription form on out-of-stock product and variant pages, theme-matched to your storefront

Per-product and per-variant (configurable/grouped child SKU) alert targeting so shoppers subscribe to the exact option they want

Automated back-in-stock transactional emails sent via Magento's TransportBuilder, respecting store view, locale, and email template theme

PO and inventory-driven restock triggers — observers on stock-update and MSI source-item events flag affected subscriptions automatically

Expected-availability date display on the product page, read from purchase-order ETA data you maintain

Cron-based dispatch queue so large subscriber batches send reliably without blocking checkout or admin

Admin subscription grid under a dedicated, ACL-gated menu with filtering, export, and per-subscriber status (pending / notified / unsubscribed)

Service contracts: repository interface + data interfaces so the alert logic is reusable across REST, GraphQL, and observers

REST and GraphQL endpoints to create, query, and cancel subscriptions for headless / PWA Studio storefronts

Multi-Source Inventory (MSI) aware — alerts fire on salable-quantity returning above zero, not just legacy stock-status flips

Double-opt-in and one-click unsubscribe support for GDPR/PECR-friendly consent handling

Store-view scoped configuration in system.xml: enable/disable, sender identity, email template, ETA visibility, and cron frequency

About this Product

Every out-of-stock product page is a leak in your funnel — a shopper who wanted to buy, found nothing to do, and left. This extension closes that leak. ECOSIRE builds, installs, and supports this module on your own Magento 2 / Adobe Commerce store — it is not an instant Adobe Commerce Marketplace download. We tailor it to your theme, your MSI (Multi-Source Inventory) setup, and your replenishment workflow before handing over a tested, production-ready install.

On any disabled/out-of-stock product or variant, customers get a "Notify me when available" form. Subscriptions are captured against the product (and the specific configurable/grouped child), stored in a custom table with a clean service contract and repository, and surfaced in the admin under a dedicated ACL-gated grid. When stock returns — whether through a manual stock update, an MSI source-item change, or an imported purchase order — an observer on the relevant inventory events flags affected subscriptions, and a cron job dispatches transactional emails via Magento's standard TransportBuilder and email templates (so they respect your store, locale, and email theme).

The expected-availability date is the differentiator: instead of a vague "we'll let you know," the product page can show when an item is due back, read from purchase-order ETA data you maintain. PO/inventory-driven triggers mean alerts fire on real availability, not guesses.

Built the right way for Magento 2: a clean module under app/code/Ecosire/StockAlert, wired through di.xml, plugins/interceptors where extension points exist, events.xml observers, plus REST and GraphQL endpoints so headless/PWA storefronts can subscribe and query too. Admin configuration lives in system.xml with full store-view scoping. Works on Magento Open Source and Adobe Commerce alike.

What you get

A complete, namespaced Magento 2 module (e.g. app/code/Ecosire/StockAlert) installed and enabled on your store

Custom database schema (declarative db_schema.xml) for subscriptions, with upgrade-safe migrations

Frontend subscription UI integrated into your theme on out-of-stock product and variant pages

Admin grid, menu, ACL resources, and system.xml configuration section

REST and GraphQL schema/resolvers for headless subscription management

Branded transactional email template wired into Magento's email theme

Cron group/job for queued alert dispatch, plus observers on the relevant inventory events

Installation on your staging/production environment, smoke testing, and a short handover doc covering config and PO-ETA data input

Who this is for

Inventory & Merchandising Manager

Runs a catalog that regularly sells out and gets restocked. Wants every out-of-stock page to capture demand and to set realistic expected-back dates from incoming purchase orders, turning stockouts into a backorder demand signal instead of lost traffic.

Ecommerce / Store Owner recovering lost sales

Knows that customers hitting an out-of-stock product usually never return. Wants an automated way to bring them back the moment stock lands — without manually emailing waitlists or pulling spreadsheets.

Magento Developer / Technical Lead

Owns the Magento 2 or Adobe Commerce build and needs an extension that follows the framework properly — service contracts, di.xml, observers, MSI awareness, GraphQL — so it survives upgrades and integrates with a headless or PWA frontend rather than hacking core.

Frequently Asked Questions about Out-of-Stock & Back-in-Stock Notification for Magento 2

Is this an instant download from the Adobe Commerce Marketplace?

No. This is a build-to-order extension. ECOSIRE develops the module, then installs it on your own Magento 2 / Adobe Commerce environment and tailors it to your theme, MSI configuration, and purchase-order workflow. You receive a tested, production-ready install — not a generic Marketplace zip you have to integrate yourself.

How long does delivery take?

Typical turnaround is about 2 to 3 weeks from kickoff for a standard build on a healthy Magento install: requirements confirmation, development, your review on staging, then production install. Heavy theme customization, complex multi-source MSI setups, or bespoke purchase-order data sources can extend this. We confirm a firm timeline before starting.

What ongoing support and updates are included?

The build includes installation, smoke testing, and a handover, plus a warranty window for fixing any defects in the delivered scope. Beyond that, we offer ongoing support and compatibility maintenance (for new Magento / Adobe Commerce minor and security releases) as a separate retainer or per-request engagement, so the module keeps working as your platform updates.

Does it work with Multi-Source Inventory and configurable products?

Yes. The module is MSI-aware: alerts fire when salable quantity returns above zero for the relevant stock, not just on a legacy in/out flag. Subscriptions target the specific child SKU of a configurable or grouped product, so a shopper waiting on one size or color is only notified when that exact option is back.

How do the expected-availability dates get populated?

The expected-back date is driven by purchase-order / replenishment ETA data. During the build we connect it to the source you maintain — a PO field, an admin-entered date per SKU, or an imported feed. When that ETA exists for an out-of-stock item, the product page can display it; when stock actually returns, the inventory-event observers trigger the emails regardless of the displayed estimate.

Can my headless / PWA storefront use it?

Yes. The module exposes REST and GraphQL endpoints to create, query, and cancel subscriptions, so a PWA Studio or other headless frontend can offer the same notify-me experience. The dispatch, admin grid, and cron logic run server-side independently of the storefront technology.
