What are the benefits of using a mailer class like Swiftmailer in PHP for sending emails from a form?

Using a mailer class like Swiftmailer in PHP for sending emails from a form provides several benefits, including better security practices, easier customization of email content, support for various email transport methods (SMTP, sendmail, etc.), and improved error handling. It also simplifies the process of sending emails by providing a clean and intuitive API. 

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

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

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