I'm confused about the $formdata transformation. If you know that you will be receiving form fields like 'email' and 'name', why not just get at them with:

$name = param('name');
$email = param('email');

Even if you don't know them, in list context CGI::param() will return the names of all of the submitted fields. You can loop over them:

foreach (param()) {
    $fields{$_} = param($_);
}
