$subject = "this is a subject";
$message = "this is a message";
mail($to, $subject, $message);
?>

Answer 1

It is not SMTP send mail. You have SMTP configurations, it is okay, but your sending way is wrong. You need to use PHPMailer package and to correct script such:
<?php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
require './PHPMailer-master/src/Exception.php';
require './PHPMailer-master/src/PHPMailer.php';
require './PHPMailer-master/src/SMTP.php';
$html = "<h1>Hello </h1>";
$mail = new PHPMailer(true);
try {
//Server settings
$mail->isSMTP();
$mail->Host = 'smtp.titan.email';
$mail->SMTPAuth = true;
$mail->Username = 'contact#domain.com';
$mail->Password = 'password';
$mail->SMTPSecure = 'ssl';
$mail->Port = 465;
//Recipients
$mail->setFrom('contact#domain.com', 'domain Team');
$mail->addAddress('receiver1#gmail.com', 'Joe User');
$mail->addAddress('receiver2#gmail.com', 'Joe User');
// Attachments
// Content
$mail->isHTML(true);
$mail->Subject = 'Here is the subject';
$mail->Body = $html;
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
$mail->send();
echo true;
} catch (Exception $e) {
echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
