I have this as my form

        <div class="contactInputs">
                <p>Send us a message</p>
                <form class="messageForm" autocomplete="on" name="contactform" method="post" action="/freequote.php">
                  <input type="text" name="name" placeholder="Name*" required>
                  <input type="text" name="companyname" placeholder="Company Name">
                  <input type="email" name="email" placeholder="Email*" required>
                    <input type="tel" name="phone" placeholder="Phone">
                    <input class="contact-submit" type="submit">
                </form>
                <textarea type="textarea" name="message" placeholder="Your Messages*" required></textarea>
                </div>

And this is the PHP used to do send the Email.

<?php
if(isset($_POST['email'])) {

$email_to = "[email protected]";
$email_subject = "Your email subject line";


function died($error) { 

    echo "We are very sorry, but there were error(s) found with the form you submitted. ";
    echo "These errors appear below.<br /><br />";
    echo $error."<br /><br />";
    echo "Please go back and fix these errors.<br /><br />";
    die();
}


if(!isset($_POST['name']) ||
    !isset($_POST['companyname']) ||
    !isset($_POST['email']) ||
    !isset($_POST['phone']) ||
    !isset($_POST['comments'])) {
    died('We are sorry, but there appears to be a problem with the form you submitted.');       
}

$name = $_POST['name'];
$companyname = $_POST['companyname'];
$email_from = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['comments'];

$error_message = "";
$email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
  if(!preg_match($email_exp,$email_from)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }
$string_exp = "/^[A-Za-z .'-]+$/";
  if(!preg_match($string_exp,$name)) {
$error_message .= 'The First Name you entered does not appear to be valid.<br />';
  }
  if(!preg_match($string_exp,$companyname)) {
$error_message .= 'The Last Name you entered does not appear to be valid.<br />';
  }
  if(strlen($message) < 2) {
$error_message .= 'The Comments you entered do not appear to be valid.<br />';
  }
  if(strlen($error_message) > 0) {
died($error_message);
  }
$email_message = "Form details below.\n\n";

function clean_string($string) {
  $bad = array("content-type","bcc:","to:","cc:","href");
  return str_replace($bad,"",$string);
}

$email_message .= "First Name: ".clean_string($name)."\n";
$email_message .= "Last Name: ".clean_string($companyname)."\n";
$email_message .= "Email: ".clean_string($email_from)."\n";
$email_message .= "phone: ".clean_string($phone)."\n";
$email_message .= "Comments: ".clean_string($message)."\n";


$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);  
?>
