Pure HTML gets in the email sent via Contact form

I have enabled it for all site messages with PHPMailer
When the user is using the contact form the receipient doesnt get an html mail but the html codes

<p><img height="90" alt="" width="72"
src="/sites/default/files/People/grilos.jpg" /></p>
<p> </p>
<p>asdfasfd</p>

Any idea why?
By the way i use a google account
