Plogins Waitlist for WooCommerce
Plogins Waitlist adds a waitlist form to out-of-stock WooCommerce products. A shopper enters their email, and when you set the product back to “In stock”, Plogins Waitlist emails everyone waiting through your site’s own WordPress mailer. There is no external service, no account to sign up for, and nothing leaves your database.
The form is rendered in PHP on the single-product summary, where it sits in the normal page flow rather than being injected after load, so it does not shift surrounding content. Submitting it runs a small vanilla-JavaScript fetch request loaded with defer in the footer; the plugin adds no jQuery of its own. On variable products it hooks into WooCommerce’s existing variation script so the form only appears once an unavailable variation is selected.
Accessibility was a first-class concern rather than an afterthought. The email field carries a visually hidden label, consent is a real required checkbox, and the success/error message is announced through an aria-live region while the form reports aria-busy during submission.
Subscriber data lives in a single {prefix}_restock_waitlist table that the plugin creates and version-tracks. Notifications fire on the woocommerce_product_set_stock_status hook, so there is no queue or background cron to run. Uninstalling drops the table and removes the plugin’s options, leaving nothing behind.
