What advantages does using a dedicated mailer class like Swift Mailer offer over manually handling email headers in PHP?

Using a dedicated mailer class like Swift Mailer offers advantages such as simplified syntax for sending emails, built-in support for attachments and inline images, automatic handling of email headers to prevent common issues like emails being marked as spam, and the ability to easily switch between different email transport methods. 

// Example code using Swift Mailer to send an email
require_once 'vendor/autoload.php'; // Include the Swift Mailer autoloader

// Create the Transport
$transport = new Swift_SmtpTransport('smtp.example.com', 25);

// Create the Mailer using your created Transport
$mailer = new Swift_Mailer($transport);

// Create a message
$message = (new Swift_Message('Wonderful Subject'))
  ->setFrom(['john.doe@example.com' => 'John Doe'])
  ->setTo(['receiver@example.com' => 'A name'])
  ->setBody('Here is the message body');

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

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