<translate><!--T:10--> We need to set a subject line and create the text body. The subject is set with [https://api.joomla.org/cms-3/classes/JMail.html#method_setSubject setSubject].</translate> 
<translate>
<!--T:11-->
The easy way to create an email body is as a string with plain text. Use the function [https://api.joomla.org/cms-3/classes/JMail.html#method_setBody setBody] to add a message to the mail body. You can also attach a file with [https://api.joomla.org/cms-3/classes/JMail.html#method_addAttachment addAttachment]. It takes a single file name or an array of file names as the argument.</translate>

<source lang="php">
$body   = "Your body string\nin double quotes if you want to parse the \nnewlines etc";
$mailer->setSubject('Your subject string');
$mailer->setBody($body);
// Optional file attached
$mailer->addAttachment(JPATH_COMPONENT.'/assets/document.pdf');
</source>

<translate><!--T:12--> If you prefer to format your email in HTML, you need to tell the mailer it is HTML. This is done with [https://api.joomla.org/cms-3/classes/JMail.html#method_isHtml isHTML]. When sending HTML emails you should normally set the [http://phpmailer.github.io/PHPMailer/classes/PHPMailer.html#property_Encoding Encoding] to base64 in order to avoid unwanted characters in the output. The subject line and any attachments are handled as above, with the exception of images embedded in the HTML. These are taken care of with the function [http://phpmailer.github.io/PHPMailer/classes/PHPMailer.html#method_addEmbeddedImage AddEmbeddedImage].</translate>

<source lang="php">
$body   = '<h2>Our mail</h2>'
    . '<div>A message to our dear readers'
    . '<img src="cid:logo_id" alt="logo"/></div>';
$mailer->isHtml(true);
$mailer->Encoding = 'base64';
$mailer->setBody($body);
// Optionally add embedded image
$mailer->AddEmbeddedImage( JPATH_COMPONENT.'/assets/logo128.jpg', 'logo_id', 'logo.jpg', 'base64', 'image/jpeg' );
</source>

<translate><!--T:13--> Normally you would leave any images on your server and refer to them with an ordinary HTML image tag, to reduce size of the mail and the time sending it.</translate>
