contact form not sending email to my specific address - forms

Question

I have a php contact form on my website. It sends me email on my normal address. But when I put in the desired mail recipient address in the 'to' section. I do not get any email. What could be the issue??
<?php
if (isset($_POST["submit"])) {
$name = $_POST['name'];
$number = $_POST['number'];
$email = $_POST['email'];
$message = $_POST['message'];
$from = ' Contact Form';
$to = '';
$subject = 'Message from Website contact page ';
$body ="From: $name\n Number: $number\n E-Mail: $email\n Message:\n $message";
// Check if name has been entered
if (!$_POST['name']) {
$errName = 'Please enter your name';
}
if (!$_POST['number']) {
$errNumber = 'Please enter your mobile number';
}
// Check if email has been entered and is valid
if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
$errEmail = 'Please enter a valid email address';
}
//Check if message has been entered
if (!$_POST['message']) {
$errMessage = 'Please enter your message';
}
// If there are no errors, send the email
if (!$errName && !$errNumber && !$errEmail && !$errMessage ) {
if (mail ($to, $subject, $body, $from)) {
$result='<div class="alert alert-success">Thank You! We will get in touch with you soon.</div>';
} else {
$result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later.</div>';
}
}
}
?>

Answer 1

can you check this:
$to = "desiredmailID#example.com, yourmailID#example.com";
// Always set content-type when sending HTML email
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
$headers .= "From: noreply#example.com" . "\r\n";
// Check if name has been entered
$errName = '';
if ($_POST['name'] == '') {
$errName = 'Please enter your name';
}
//Other validation messages here...
// If there are no errors, send the email
if ($errName == '' && $errNumber == '' && $errEmail == '' && $errMessage == '' ) {
if (mail ($to, $subject, $body, $headers)) {
$result='<div class="alert alert-success">Thank You! We will get in touch with you soon.</div>';
} else {
$result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later.</div>';
}
