How can the use of external libraries like PHPMailer or SwiftMailer enhance the functionality and reliability of email sending within PHP scripts in Wordpress?

Using external libraries like PHPMailer or SwiftMailer can enhance the functionality and reliability of email sending within PHP scripts in WordPress by providing more robust features, better error handling, and improved security measures compared to the built-in `wp_mail` function. These libraries offer more customization options, support for various email protocols, and better handling of attachments and HTML content. 

// Example PHP code snippet using PHPMailer to send an email in WordPress

require_once('path/to/PHPMailerAutoload.php');

// Create a new PHPMailer instance
$mail = new PHPMailer;

// Set up the email parameters
$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;

$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Subject of the email';
$mail->Body = 'Body of the email';

// Send the email
if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}
