Account Activation Email Question

[everythingis]

I'm sending an email when a user registers, but the content is not showing up in the email body. There's an attachment that comes, so just wondering what the heck I'm doing wrong here.

    $to = "$email";
    $from = "[e-mail]";
    $subject = "so.did.we registration link";
    $message = 

   "Hi $firstname,

   Please complete this step to activate your new account at so.did.we.

   Click, or copy and paste the link below into your browser address bar:

   http://www.sodidwe.com/activation.php?id=$user_id&sequence=$db_password

   Use these to sign in to the member area after account activation:
   Username: $username
   Password: $password

   See you on the site!
   [e-mail]

   so.did.we
   where strangers become friends"   

   ;
   //end of message
	$headers  = "From: $from\r\n";
    $headers .= "Content-type: text\r\n";

mail($to, $subject, $message, $headers);

   $msgToUser = "<h2>One Last Step!</h2>$firstname, thank you for registering with so.did.we.<br />
   In a moment you will be sent an email with an activation link for your account.<br /><br />
   <br />
   <strong><font color=\"#990000\">If you do not receive, or cannot activate your account, please contact the so.did.we team at: [e-mail].</font></strong> 
   ";

   include_once 'user_message.php'; 

   exit();

   }

try it with out the content type header, that's the only issue i see that could be causing it.

You could also try
Content-type: text/plain

The rfc says -

Content-type: text/plain; charset=us-ascii

is the default, i have never bothered with it when using mail(), but mail() shouldn't be used for much its very limited.
