PHPMailer sending multiple emails to every receipents in database - php

Question

I am using this code to send email to everyone in the database in a loop. Problem occurred when I find out that user 1 in database also getting all emails sent to other users in the database. User 2 gets all email sent to other users after him and so on. I want to send a single email to everyone customized with their name and emails. Did check and applied couple of solutions from this forum but they are not working.
#SEND EMAILS
require '../includes/PHPMailer/PHPMailerAutoload.php';
require '../includes/PHPMailer/config.php';
if(isset($_POST['submit'])){
$mail = new PHPMailer;
$mail->isSMTP();
$mail->SMTPAuth = true;
$mail->Host = $smtp_server_w;
$mail->Username = $username_w;
$mail->Password = $password_w;
$mail->SMTPSecure = "ssl";
$mail->Port = 465;
$mail->setFrom("test#test.com", "Test Name");
$sql_mail = "SELECT * FROM users";
$run_mail = mysqli_query($conn, $sql_mail);
while ($row_mail = mysqli_fetch_assoc($run_mail)) {
$name = $row_mail["user_name"];
$email = $row_mail["user_email"];
$mail->ClearAddresses();
$mail->addAddress('test#test.com', 'Test Name');
$mail->addBCC($email, $name);
$mail->isHTML(true); // Set email format to HTML
$bodyContent = "<p>Multiple Messages</p>";
$mail->Subject = $row_mail['user_name'].", New job is available " ;
$mail->Body = $bodyContent;
$mail->AltBody = $bodyContent;
if(!$mail->send()) {
echo "Message could not be sent.";
$error = '<div class="alert alert-danger"><strong>Mailer Error: '. $mail->ErrorInfo.'</strong></div>';
} else {
$error = '<div class="alert alert-success"><strong>Message has been sent</strong></div>';
}
}
}
