How to fix contact form email not working in PHP?

I created a contact form in PHP, but it is not sending emails from my website.

My contact form doesn't work perfectly, and after uploading it to a live server like cPanel or hPanel, emails are not being delivered. When a user submits the contact form, the form is submitted successfully, but I don't receive any emails in my inbox.

I have tried using the PHP mail() function, but it is not working on my hosting server. I also contacted my hosting provider, but they couldn't resolve my problem.

I am using Hostinger hPanel and GoDaddy cPanel hosting.

if(isset($_POST['sub']))
			{ 
          $name=$_POST['name']; 
       $email=$_POST['email']; 
        $msg=$_POST['msg']; 
       $phone=$_POST['phone']; 
       $FromName="My Website Title";
$FromEmail="info@mywebsite.com";
$ReplyTo=$email;
$toemail="mytoemail@gmail.com";
$subject="Contact Form"; 
$message='Name:-'.$name.'<br>Email :-' .$email.'<br> Phone No:-'.$phone.'<br> Message:-'.$msg;
$headers = "MIME-Version: 1.0\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\n";
$headers .= "From: ".$FromName." <".$FromEmail.">\n";
$headers .= "Reply-To: ".$ReplyTo."\n";
$headers .= "X-Sender: <".$FromEmail.">\n";
$headers .= "X-Mailer: PHP\n";
$headers .= "X-Priority: 1\n";
$headers .= "Return-Path: <".$FromEmail.">\n";
   if(mail($toemail, $subject, $message, $headers,'-f'.$FromEmail) ){
          $hide=1;
        
         echo 'Sent'; 
	      
	} else {
		echo "Failed";
} 

			}
