Digages

Digages Restock Alert adds a “Notify Me When Available” button to out-of-stock WooCommerce product pages. Customers subscribe with one click (logged-in) or by entering their email (guests). When stock is replenished, the plugin automatically dispatches personalized email alerts — recovering sales that would otherwise be lost.
<h4>Key Features</h4>
Notify Me Button 
Appears automatically on the single product page whenever a product’s stock hits zero. Logged-in users subscribe in one click; guests enter their email address in a clean inline form.
Automatic Email Notifications 
The plugin watches for WooCommerce stock status changes. When a product transitions from out-of-stock to in-stock, email alerts are dispatched to all active subscribers via WordPress Cron — keeping your page load times unaffected.
Admin Subscriber Dashboard 
A dedicated admin screen lists every subscriber with their product, email, subscription date, and last-notified date. You can search by email, paginate through large lists, remove individual subscribers, and manually trigger alerts for any product.
Export to CSV 
Export the full subscriber list as a CSV file with one click — useful for audits, backups, or importing into external email tools.
Smart Alert Rules 
Control when alerts fire:
<ul>
<li>Set a minimum stock quantity before alerts are sent (e.g. only alert when qty ≥ 5).</li>
<li>Limit the number of notifications sent per batch.</li>
<li>Optionally restrict each subscriber to receiving only one alert per product.</li>
</ul>
Urgency Builder 
Alert emails automatically include a live stock count line (“Only 7 items left!”) when stock is low, encouraging immediate action.
Auto Discount Coupon 
Optionally generate a unique, single-use WooCommerce percentage-off coupon for each subscriber’s alert email — rewarding them for their patience and boosting conversion.
Analytics Dashboard 
Track performance across your entire alert program:
<ul>
<li>Total active subscribers</li>
<li>Total subscriptions recorded</li>
<li>Emails sent</li>
<li>Orders placed from alert emails (conversion tracking)</li>
<li>Conversion rate percentage</li>
<li>Bar chart of top products by subscriber demand</li>
</ul>
Priority Sending 
Enable priority mode to dispatch alerts immediately when stock changes, bypassing the default 30-second cron delay.
Shortcode Support 
Embed the notify form anywhere on your site using <code>[digages_psas_notify_form product_id="123"]</code>.
WooCommerce Standards Compliant 
Built on WooCommerce hooks, nonces on every action, all inputs sanitized and unslashed, all outputs properly escaped, assets loaded via <code>wp_enqueue_style</code> / <code>wp_enqueue_script</code>.

Australcode Back In Stock turns out-of-stock products into recovered sales. It is privacy-first (double opt-in and explicit consent built in), sends through Action Scheduler so big waiting lists never time out, and keeps every core feature free (Pro adds restock coupons, recovered-revenue tracking, SMS/WhatsApp alerts, email-marketing sync and webhooks). When a product is sold out, a “Notify me when available” form appears on the product page. Customers leave their email, and the moment you restock they get an automatic email with a link straight to it.
No more lost sales because a customer couldn’t be bothered to check back.
<h4>How it works</h4>
<ol>
<li>A product runs out of stock.</li>
<li>A subscribe form appears on the product page (simple and variable products).</li>
<li>Customers enter their email — optionally confirming it first (double opt-in).</li>
<li>You restock the product.</li>
<li>Everyone on the waiting list gets an automatic email with a link to buy it.</li>
<li>Customers can unsubscribe with one click from any email.</li>
</ol>
<h4>Free features</h4>
<ul>
<li>“Notify me when available” form on out-of-stock products (simple and variable).</li>
<li>Shortcode and Gutenberg block to place the form anywhere — works with any page builder; add <code>mode="product"</code> for popups and modals (Elementor, Divi).</li>
<li>Automatic restock email with the product’s photo, price and a direct link — a card built to win the sale back, not just notify.</li>
<li>Per-product subscriber list in the admin, with KPIs, a “Top demand” panel, status filters and email search.</li>
<li>Optional double opt-in (email confirmation before subscribing).</li>
<li>Optional consent checkbox (privacy-law friendly).</li>
<li>One-click unsubscribe from every email.</li>
<li>Reliable background sending via Action Scheduler — works for products with hundreds of subscribers without timing out.</li>
<li>Cache and CDN proof — the form fetches a fresh security token at submit time, so it keeps working behind full-page edge caches like Cloudflare and Kinsta.</li>
<li>Developer hooks — PHP actions and filters (<code>acbis_after_subscribe</code>, <code>acbis_email_args</code>) plus an <code>acbis:subscribed</code> JavaScript event, to wire signups into your CRM, analytics or email tool.</li>
<li>Customizable button label and email subject/heading text.</li>
</ul>
<h4>Pro features</h4>
<ul>
<li>Restock coupons — include a unique, single-use discount in each restock email. It is applied automatically at checkout (no copy-pasting), is restricted to the product and the customer’s email, and expires after the window you choose, so the urgency is real.</li>
<li>Recovered-revenue tracking — a dashboard that attributes paid orders back to your restock coupons, so you see exactly how many sales and how much revenue the waiting list brings back.</li>
<li>SMS & WhatsApp alerts — reach customers on their phone too, through your own Twilio account. Opt-in only: the customer adds their number and ticks a separate consent box, and the alert goes out by SMS and/or WhatsApp alongside the email.</li>
<li>Email-marketing sync — every subscriber is automatically added to your Klaviyo list or Mailchimp audience (bring your own API key), so you can build flows and segments around real back-in-stock demand.</li>
<li>Webhooks & demand alerts — fire a signed JSON webhook on every signup and restock (wire it to Zapier, Make, n8n or your own endpoint), and get a Slack or Discord ping the moment a product passes a demand threshold you set. Turn the waiting list into an inventory signal for your team.</li>
<li>Export the subscriber list to CSV (per product, with status and dates).</li>
</ul>

<h4>Privacy</h4>
The plugin sends restock emails through your own site (<code>wp_mail</code> / your SMTP). The free plugin never sends your subscribers’ data to any third-party service: emails are stored in your own database, and the IP used for anti-abuse rate limiting is stored hashed, never in clear text. Two optional integrations are off by default: the Pro SMS/WhatsApp feature sends the phone number you collect — with the customer’s separate consent — to Twilio to deliver the message, and Freemius handles licensing and updates. Both are described under “External services” below.
<h3>External services</h3>
<h4>Freemius (account, licensing & secure checkout)</h4>
Australcode Back In Stock uses Freemius as its billing and licensing platform (Freemius is the Merchant of Record for Pro purchases). Connecting to Freemius is optional: on activation you can click “Skip” and the plugin stays fully functional without ever contacting Freemius.
<ul>
<li>If you opt in (free or Pro), the plugin sends your admin email, site URL and basic environment data (WordPress, PHP and plugin versions) to the Freemius API (host <code>api.freemius.com</code>, path <code>/v1/</code>) to create your account and check for updates.</li>
<li>If you activate a Pro license, the plugin sends your license key and site domain to Freemius to validate the license and enforce the per-plan site limit. The license is re-validated periodically.</li>
<li>Purchases and license management happen on Freemius-hosted pages (hosts <code>freemius.com</code>, <code>users.freemius.com</code>).</li>
</ul>
No data is sent to Freemius if you skip the opt-in and do not enter a license key.

<li>Privacy Policy: https://freemius.com/privacy/</li>
</ul>
<h4>Twilio (SMS & WhatsApp delivery — Pro, optional)</h4>
The Pro “SMS & WhatsApp alerts” feature is off by default and only works if you enable it and enter your own Twilio credentials. When a subscriber has given phone consent and a product is restocked, the plugin sends the subscriber’s phone number and the message text to the Twilio API (host <code>api.twilio.com</code>, path <code>/2010-04-01/</code>) so Twilio delivers the SMS/WhatsApp. Your Twilio Account SID and Auth Token are stored encrypted in your database and used only to authenticate these requests. No data is sent to Twilio unless you enable a channel and configure credentials.
<ul>
<li>Terms of Service: https://www.twilio.com/legal/tos</li>
<li>Privacy Policy: https://www.twilio.com/legal/privacy</li>
</ul>
<h4>Klaviyo & Mailchimp (email-marketing sync — Pro, optional)</h4>
The Pro “Email marketing sync” feature is off by default and only works if you enable a provider and enter your own API key. When a customer subscribes to a back-in-stock alert, the plugin sends their email address to the provider you enabled — Klaviyo (host <code>a.klaviyo.com</code>) or Mailchimp (host <code><dc>.api.mailchimp.com</code>) — to add them to the list/audience you choose. Your API key is stored encrypted in your database and used only to authenticate these requests. No data is sent unless you enable a provider and configure it.
<ul>
<li>Klaviyo — Terms: https://www.klaviyo.com/legal/website-terms-of-use · Privacy: https://www.klaviyo.com/legal/privacy-policy</li>
<li>Mailchimp — Terms: https://mailchimp.com/legal/terms/ · Privacy: https://mailchimp.com/legal/privacy/</li>
</ul>
<h4>Webhooks & Slack/Discord demand alerts (Pro, optional)</h4>
The Pro “Webhooks & demand alerts” feature is off by default and only sends data to URLs you configure — it is not tied to any service we operate. When you set a webhook URL, the plugin POSTs a small JSON payload (event type, customer email, product ID and name, timestamp) to that URL on each signup and restock, signed with an HMAC-SHA256 <code>X-Acbis-Signature</code> header so your endpoint can verify it. When you set a Slack or Discord incoming-webhook URL and a demand threshold, it POSTs a short text message to that URL when a product reaches the threshold. The destinations are entirely yours (for example Zapier, Make, n8n, Slack or Discord); review the terms and privacy policy of whichever service you point them at. No data is sent unless you enter a URL.
