What are the advantages of using a Mailer class like Swift Mailer over the built-in mail() function in PHP for sending bulk emails?

When sending bulk emails in PHP, using a Mailer class like Swift Mailer offers several advantages over the built-in mail() function. Swift Mailer provides a more robust and flexible API for handling email sending tasks, including support for attachments, HTML emails, and various transport options. It also offers better performance and error handling capabilities compared to the basic functionality provided by mail(). 

// Example PHP code using Swift Mailer to send bulk emails

// Include the Swift Mailer autoloader
require_once 'path/to/vendor/autoload.php';

// Create a new instance of the Swift Mailer class
$mailer = new Swift_Mailer(new Swift_SmtpTransport('smtp.example.com', 587));

// Create a message
$message = (new Swift_Message('Subject of the email'))
    ->setFrom(['your@email.com' => 'Your Name'])
    ->setTo(['recipient1@email.com', 'recipient2@email.com'])
    ->setBody('Hello, this is the content of the email.');

// Send the message
$result = $mailer->send($message);

if ($result) {
    echo 'Email sent successfully.';
} else {
    echo 'Failed to send email.';
}
