What are the advantages of using a Mailer class over PHP's built-in mail function for sending HTML emails?

Using a Mailer class for sending HTML emails provides several advantages over PHP's built-in mail function. The Mailer class typically offers more robust features such as support for SMTP authentication, easier handling of attachments, better error handling, and the ability to easily customize email headers. Additionally, using a Mailer class can make the code more organized and maintainable. 

// Example code using PHPMailer class for sending HTML emails
require 'vendor/autoload.php'; // Include PHPMailer autoloader

// Create a new PHPMailer instance
$mail = new PHPMailer\PHPMailer\PHPMailer();

// Set up SMTP configuration
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your@example.com';
$mail->Password = 'your_password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

// Set email content
$mail->isHTML(true);
$mail->Subject = 'Subject of the email';
$mail->Body = '<h1>This is an HTML email</h1>';

// Add recipients
$mail->addAddress('recipient@example.com', 'Recipient Name');

// Send the email
if($mail->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Error sending email: ' . $mail->ErrorInfo;
}
