What are the advantages of using a Mailer class like Swiftmailer for sending emails in PHP?

Using a Mailer class like Swiftmailer in PHP offers several advantages for sending emails, such as better performance, built-in support for various email transport methods (SMTP, sendmail, etc.), easy integration with popular email services like Gmail and Mailgun, and improved security features to prevent email spoofing and abuse. 

// Example PHP code snippet using Swiftmailer to send an email
require_once 'vendor/autoload.php';

// Create the Transport
$transport = (new Swift_SmtpTransport('smtp.example.org', 25))
  ->setUsername('your_username')
  ->setPassword('your_password');

// 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';
}
