mail() PHP not work

I tried to use the mail() php function in the contact form, but I never received it. Does your free hosting not provide the functionality of PHP mail()?

this is my code

<?php
if (isset($_POST['submit']))
{
$emailTo = '[email protected]';
$name = addslashes(trim($_POST['Name']));
$clientEmail = addslashes(trim($_POST['Email']));
$subject = addslashes(trim($_POST['Subject']));
$message = addslashes(trim($_POST['Message']));

if($clientEmail !='' && $subject != '' && $message != '' && $name != '') {
    // Send email
    $headers = From:  . $clientEmail .  < . $clientEmail . > . 
<br> . Reply-To:  . $clientEmail;

    mail($emailTo, $subject .  (Form [email protected]), $message, $headers);
}
echo <meta http-equiv=
efresh content=; url=index.php>;
}
?>
