When handling email delivery/read receipts in PHP, it is recommended to use a library like PHPMailer which provides a more robust and reliable way to send emails. PHPMailer supports features like read receipts and delivery notifications, making it easier to track email interactions. By using PHPMailer, you can ensure that your emails are delivered successfully and monitor their status. 

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'your@example.com';
    $mail->Password = 'yourpassword';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;

    $mail->setFrom('your@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');
    
    $mail->Subject = 'Testing read receipts';
    $mail->Body = 'This is a test email with read receipts enabled';

    $mail->ConfirmReadingTo = 'your@example.com';

    $mail->send();
    echo 'Email sent successfully';
} catch (Exception $e) {
    echo 'Email could not be sent. Mailer Error: ' . $mail->ErrorInfo;
}
