Answer 1

You have made some mistakes. Use the below code:
<?php
$name = $_POST['contact_name'] ;
$email = $_POST['contact_email'] ;
$company = $_POST['contact_company'] ;
$number = $_POST['contact_phone'] ;
$message = $_POST['contact_message'] ;
//modify the mail function
mail("allycallow#hotmail.com", $name.$company, $message, "From:" . $email);
?>
And in JS change the below:
success: function(returnData) {
$('.success').fadeIn(1000);
$("input[type=text], textarea").val("");
//$('.success').fadeToggle(1000);
}
