Help with sending online form results to email

Could someone please help me figure out why my PHP isn't working. I've built an online form for customers to fill out, and then on submit it should send to a designated email. However, the form works but the email doesn't. Any help please!!

Here's the php I'm using:

<?

//Destination Email ID

$to = "dest";



//Name of the Person

$namenew = $_GET['name'];



//Email Id of the person

$emailnew = $_GET['email'];



//Feedback detail

$feedbacknew = $_GET['feedback'];



//Subject line of the email

$subject = "Feedback Form"." "."$emailnew";



/*********** Email body *******************/

$matter = "Below are the details filled by"." "."$namenew"."nn".

"Name:"." "."$namenew"."nn".

"Email:"." "."$emailnew"."nn".

"Suggestion:"." "."$feedbacknew"."nn";

/**********************************************/





mail("$to", "$subject","$matter","From: $emailnew");



?>
