What are the benefits of using Mailer classes over the raw mail() function in PHP for sending emails?

Using Mailer classes over the raw mail() function in PHP for sending emails offers several benefits such as easier configuration, better error handling, support for attachments and HTML emails, and improved security features like SMTP authentication. Mailer classes provide a more object-oriented approach to sending emails, making code more organized and maintainable. 

// Using PHPMailer library for sending emails
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

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

    //Recipients
    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.net', 'Recipient Name');

    //Content
    $mail->isHTML(true);
    $mail->Subject = 'Subject';
    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
    $mail->AltBody = 'This is the plain text message body';

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