asynchronous email php + jquery - php

Question

I need to send email asynchronously.
For that I have a jQuery ajax client and PHP backend to actually send eMail, still AJAX's success method is not being called. I understand it is simple, but yet doesn't seem to be working. Can somebody please take a look at my code and see what I'm doing wrong? Really appreciate it.
$.ajax({
type: "POST",
url: "mail.php",
data: {name: "manu", email: "abc#abc.com"},
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
alert('mail sent');
$('#divToBeWorkedOn').html(msg);
}
});
and I have mail.php
<?php
header("Content-type: application/json");
$name = trim($_POST['name']);
echo $name
$email = trim($_POST['email']);
$msg="my email";
$emailTo = 'myemail#gmail.com';
$subject = 'Contact Form Submission from '.$name;
$sendCopy = trim($_POST['sendCopy']);
$body = "Name: $name \n\nEmail: $email \n\nMessage: $message";
$headers = 'From: Saddi website <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email;
mail($emailTo, $subject, $body, $headers);
echo 1;
?>

I see 2 problems.
you're echoing just 1, its not JSON. So in your PHP code do json_encode("msg"=>"1");
In my experience, if you have this
header("Content-type: application/json");
OR header("Content-type: json/text");
You won't get any result in jquery success or error blocks.
success: function(msg) {
alert(msg);
}
the msg would return null value (or nothing). The alert will happen but will show something like object object.
