Reply To: How to override existing variables or creating custom variables

[Marco Michely]

Here’s an easy solution:

function mwe_action_mail_to( $email_to ) {

    $admin_email = get_bloginfo('admin_email');

    foreach($email_to as $key => $email) {
        if(str_contains($email, $admin_email)) {
            $email_to[$key] = "My Name <my@domain.com>";
        }
    }
    
    return $email_to;

}
add_filter('wsf_action_email_to', 'mwe_action_mail_to');
