原文外掛簡介
WT Waitlist is a “back in stock” waitlist for WooCommerce without bloat. Customers leave their email on an out-of-stock product page, and when the stock returns – the plugin sends a notification in the background through Action Scheduler.
Built by the webmasters.team team. Open-source code, no external APIs, all data stored locally in the WordPress database.
Key features
Signup form replaces Add to cart for out-of-stock products, with variation support (per size/color).
Custom database tables ({prefix}_waitlist_subscriptions) – we do not clutter wp_postmeta, the plugin scales to tens of thousands of subscriptions.
Action Scheduler queue (bundled with WooCommerce): batch of 50 emails per tick, automatic retries, retry log visible in WooCommerce → Status → Scheduled Actions.
5 min throttle per product – prevents duplicate sends when multiple hooks fire (e.g. quantity change followed by status change).
One-click unsubscribe via a link in the email (SHA-256 token), no confirmation or login required.
GDPR-ready: consent logging (anonymized IP, timestamp, user agent), integration with WordPress Privacy Tools (export and erasure of data per email).
CSV export of subscribers from the admin panel (streamed, no timeouts on large lists).
Anti-spam: honeypot plus rate limiter per IP (10 submissions per hour).
Theme compatibility: classic themes (Storefront, Twenty Twenty-One/Two/Three) plus block themes (Twenty Twenty-Four/Five) – the form attaches through a hook for classic templates and through a render_block filter for FSE.
Zero external dependencies: apart from WooCommerce, requires only plain PHP 8.0+.
Shortcode fallback
[wt_waitlist product_id="123"] - use this if your custom product template does not fire the standard hooks.
What WT Waitlist does NOT do (by design)
No SMS, no Mailchimp/MailerLite integrations in the free version.
No double opt-in (minimal flow – leave email, get notification).
No WYSIWYG editor for email templates (HTML template lives in the plugin file, override with the wt_waitlist/notification_context filter).
These features are planned for the Pro edition. The free edition covers 100% of the core waitlist flow.
