email line breaks

[pauldreed]

I have a php contact page form which sends enquiries to my email account and also a confirmation email to the sender, telling them that I will respond in due course.
This works great, but how can I introduce a line break/new paragraph into the automated email, so the email looks formatted and not just a long string of words??
[code]# send confirmation email
if($sendnotification == true) {
$notification_message = "Thank you for contacting $websitetitle, $sender_name. We have received your email and will be in touch shortly";
$notification_subject = "Thanks for your message to $websitetitle.";
mail($sender_email, $notification_subject, $notification_message, "From: $recipient");
            header('Location: http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].'?success');
        }[/code]

\n - Newline. "this is some text\n this is on a new line"

Works only in double quotes.

Thanks, that works great, are you aware of any other formatting options that I could use?
