I couldn't add a comment to Mohammad Saqib's answer, but I wanted to say that you shouldn't use
as a replacement for \r\n because this may cause the email to be caught by 'line too long' spam filters. New lines are important to keep the email more human and allow successful delivery!

The method I recommend is:

$output[] = "line 1";
$output[] = "line 2";
$EmailBody = join("\r\n",$output);

Also you must make sure you 'sanitize' headers to avoid header injection from user input, here is a function that is double sure to stop injection:

function sanitize(&$data){
   return str_ireplace(array("\r", "\n", "%0a", "%0d"), '', stripslashes($data));
}


$headers = 'From: '.sanitize($email);

If you wanted HTML tags to show in the email, change the type using the header:

$headers = 'Content-type: text/html;\r\nFrom: '.sanitize($email);

If you did display HTML, you should clean the user input to avoid anything unexpected... i.e. HTML injection. Use this function anywhere you display user input in HTML:

function htmlclean($str){
    return htmlentities($str, ENT_QUOTES);
}

e.g. $body = "Brand Name: " . htmlclean($brandname);
