Hi Guys
There is the filter for content type though I have never got it to work or find anyone who has got it to work. Instead the the trick is to build a custom header with the MIME, Content Type. Below is an example.
$headers= "MIME-Version: 1.0\n" .
"From: Me <[email protected]>\n" .
"Content-Type: text/html; charset=\"" .
get_option('blog_charset') . "\"\n";
wp_mail($emailaddress, $subject, $content, $headers);
