This wordpress plugin utilizes our daily dump of disposable email address domains to detect the use of disposable email addresses.
It uses the WordPress internal <a href="https://developer.wordpress.org/reference/hooks/is_email/" rel="nofollow ugc">is_email</a> hook, therefore it integrates seamlessly into 3rd party plugins like WooCommerce, Gravity Forms, Jetpack and every other plugin that uses the <a href="https://developer.wordpress.org/reference/functions/is_email/" rel="nofollow ugc">is_email()</a> function.
