What are the advantages of using SMTP with SwiftMailer for sending emails in PHP?

When sending emails in PHP, using SMTP with SwiftMailer offers several advantages such as better deliverability, improved error handling, support for attachments, and the ability to send emails asynchronously. This can help ensure that emails are successfully delivered to recipients' inboxes and provide more robust functionality for sending emails programmatically. 

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

// Create the Transport
$transport = (new Swift_SmtpTransport('smtp.example.com', 587, 'tls'))
  ->setUsername('your_smtp_username')
  ->setPassword('your_smtp_password');

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

// Create a message
$message = (new Swift_Message('Subject'))
  ->setFrom(['your@example.com' => 'Your Name'])
  ->setTo(['recipient@example.com' => 'Recipient Name'])
  ->setBody('Hello, this is a test email sent using SMTP with SwiftMailer.');

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

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