Port of the Postmark API in Kohana 2.3.4. It might be easily portable to Kohana 3.0.
Based on http://github.com/Znarkus/postmark-php/blob/master/Postmark.php
Example
$email = new Postmark(); $email->to('EMAIL ADDRESS', 'NAME') ->subject('SUBJECT OF THE EMAIL') ->tag('MIGHT BE ANYTHING YOU WANT') ->messageHtml('A STRING, A VIEW or WHATEVER') ->send();
