I'm using the following for $headers:
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$headers .= "From: " . $from . "\r\n";
$headers .= "Reply-To: ". $from . "\r\n";
$headers .= "CC:
[email protected]\r\n";
My html looks fine in Gmail, however, it appears as raw html in outlook.
Did I forget something in the header?
