Are there any best practices for integrating PHP mailer classes into existing code for sending emails?

When integrating PHP mailer classes into existing code for sending emails, it is important to follow best practices to ensure smooth functionality. One common approach is to create a separate email handling class that encapsulates the mailer functionality, making it easier to manage and reuse across different parts of the codebase. Additionally, it is recommended to use SMTP authentication for sending emails securely and to handle error messages gracefully to provide feedback to the user in case of any issues. 

// Include the PHPMailer library
require 'path/to/PHPMailer/PHPMailerAutoload.php';

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

// Set up SMTP configuration
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your_smtp_username';
$mail->Password = 'your_smtp_password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

// Set email content
$mail->setFrom('from@example.com', 'Sender 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';
}
