Unsure why this is not working  debug is showing no issues

if (isset($_GET['kudoemaildelete'])) {
    //data removal code  will be going here
        $kuemid = $_GET['kuemid'];

        for($i=0;$i<count($kuemid);$i++){
        $del_id = $kuemid[$i];

    $wpdb->query(
              'DELETE  FROM '.$wpdb->prefix.'kudos_email
               WHERE kuemid  IN($del_id)'
);



    $adminurl = get_admin_url();
    $redirurl = $adminurl."admin.php?page=kudos";



echo "Removing emails if not returned in 5 seconds <a href=" .$redirurl . ">click here</a>";

# echo("<script>location.href = '".$redirurl."';</script>");
 }
} else {
