To send a message without using a template, simply pass the body of the message as a string (or an array of lines) to the send() method. For example:

$this->Email->from    = 'Somebody <somebody@example.com>';
$this->Email->to      = 'Somebody Else <somebody.else@example.com>';
$this->Email->subject = 'Test';
$this->Email->send('Hello message body!');

1. $this->Email->from = 'Somebody <somebody@example.com>';
2. $this->Email->to = 'Somebody Else <somebody.else@example.com>';
3. $this->Email->subject = 'Test';
4. $this->Email->send('Hello message body!');
