Wonderful Disposable Email Blocker is a WordPress plugin designed to prevent the use of disposable or temporary email addresses on WordPress sites. The tool addresses issues caused by spam bots and users who exploit throwaway inboxes to register accounts, place fake orders, or post comments with email addresses that become inactive shortly after use. By referencing a list of thousands of known disposable email domains, the plugin checks submitted email addresses and enables site administrators to block their use in several areas. The plugin allows independent blocking in four specific contexts: WordPress registration forms (such as wp-login.php), WooCommerce account registration forms, the billing email field during WooCommerce checkout, and the comment submission process. This flexibility is highlighted by its ability to cover WooCommerce-specific registration hooks, which may be missed by plugins that only monitor standard WordPress registration forms. Additionally, the plugin supports custom block and allow lists, giving site owners control over which email domains are permitted or denied beyond the default list.
