A Waitlist plugin allows you to successfully handle promotional campaigns for a product or service before it is actually available: you can just enable a “wait list” option and offer subscribers a discount or a special promotion.
But it’s not just that: it is also a key took to prevent losing perspective customers and therefore sales in case one of your store products goes out of stock and you need time to restock it.

Einfaches Plugin und keine Hexerei notwendig.
ok, my initial review was “it simply doesn’t work”, but with help of chatGPT and 4h of dedication i managed to fix this.
Just add this code as a snippet:
function trigger_yith_waitlist_emails_for_all_products( $product_id ) {
$product = wc_get_product( $product_id );
if ( $product && $product->is_in_stock() ) {
YITH_WCWTL_Mailer()->schedule_email_send( $product );
error_log('Scheduled YITH Waitlist Email for Product ID ' . $product_id);
}
}
add_action( 'woocommerce_product_set_stock_status', 'trigger_yith_waitlist_emails_for_all_products', 10, 1 );
