Kohana-communicate is a project mainly written in PHP, it's free.
An email wrapper class for sending emails (no newsletters). Postmark Provider included
This Email-wrapper class for Kohana 3.0 doesn't have a proper documentation yet. When there is some spare time, I will write the guide. The code is "documentated" inside the class.
How to use:
$mail = Communicate::factory('postmark');
$mail->setup()
->addTo('[email protected]', 'Your name')
->addFrom('[email protected]')
->addMessage($htmlbody, $textbody)
->addSubject('testemail');
if($mail->send())
{
//success
}
