I don't think I'm following the 2nd half of your post, but a simple example of sending an email in Craft 2 looks like this:


    $emailModel = new Craft\EmailModel();

    $emailModel->subject = 'My Subject';
    $emailModel->body = 'My Body';
	$emailModel->htmlBody = '<html><body>My HTML Body</body></html>';
    $emailModel->toEmail = '[email protected]';

    craft()->email->sendEmail($emailModel);
