原文外掛簡介
Australcode Back In Stock is a back in stock notifier and waitlist for WooCommerce that 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, Klaviyo & Mailchimp 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.
How it works
A product runs out of stock.
A subscribe form appears on the product page (simple, variable, grouped and subscription products).
Customers enter their email — optionally confirming it first (double opt-in).
You restock the product.
Everyone on the waiting list gets an automatic email with a link to buy it.
Customers can unsubscribe with one click from any email.
Free features
“Notify me when available” form on out-of-stock products — simple, variable, grouped and subscription products (a per-item form on grouped products).
Shortcode and Gutenberg block to place the form anywhere — works with any page builder; add mode="product" for popups and modals (Elementor, Divi).
Automatic restock email with the product’s photo, price and a direct link — a card built to win the sale back, not just notify.
Per-product subscriber list in the admin, with KPIs, a “Top demand” panel, status filters and email search.
Optional double opt-in (email confirmation before subscribing).
Optional consent checkbox (privacy-law friendly).
One-click unsubscribe from every email.
Reliable background sending via Action Scheduler — works for products with hundreds of subscribers without timing out.
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.
Developer hooks — PHP actions and filters (acbis_after_subscribe, acbis_email_args) plus an acbis:subscribed JavaScript event, to wire signups into your CRM, analytics or email tool.
Customizable button label and email subject/heading text.
Pro features
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.
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.
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.
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.
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.
Export the subscriber list to CSV (per product, with status and dates).

Privacy
The plugin sends restock emails through your own site (wp_mail / 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.
External services
Freemius (account, licensing & secure checkout)
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.
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 api.freemius.com, path /v1/) to create your account and check for updates.
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.
Purchases and license management happen on Freemius-hosted pages (hosts freemius.com, users.freemius.com).
If you open the “Contact Us” screen, the support form is loaded from Freemius and whatever you type there (your name, email address and message) is sent to Freemius so they can route it to us. Nothing is sent unless you submit the form.
Apart from the support form, no data is sent to Freemius if you skip the opt-in and do not enter a license key.

Twilio (SMS & WhatsApp delivery — Pro, optional)
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 api.twilio.com, path /2010-04-01/) 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.

Klaviyo & Mailchimp (email-marketing sync — Pro, optional)
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 a.klaviyo.com) or Mailchimp (host
Klaviyo — Terms: https://www.klaviyo.com/legal/website-terms-of-use · Privacy: https://www.klaviyo.com/legal/privacy-policy
Mailchimp — Terms: https://mailchimp.com/legal/terms/ · Privacy: https://mailchimp.com/legal/privacy/
Webhooks & Slack/Discord demand alerts (Pro, optional)
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 X-Acbis-Signature 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.
