$mail->addAddress('', 'Recepient Name');
$mail->Username = 'Your AWS SMTP User Name';
$mail->Password = 'Your AWS SES SMTP Password';
$mail->addCustomHeader('X-SES-CONFIGURATION-SET', 'ConfigSet');

/* The alternative email body; this is only displayed when a recipient
opens the email in a non-HTML email client. The \r\n represents a
line break.*/
$mail->AltBody = "Email Test\r\nThis email was sent through the Amazon SES SMTP interface using the PHPMailer class.";
