Are there any specific considerations or best practices to keep in mind when handling errors or invalid email addresses while using PHPMailer for mass email sending?

When handling errors or invalid email addresses while using PHPMailer for mass email sending, it is important to implement error handling to catch any issues that may arise. One approach is to use try-catch blocks to handle exceptions thrown by PHPMailer when sending emails to invalid addresses. This way, you can log the error or take appropriate action, such as skipping the invalid email address. 

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

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

try {
    // Attempt to send the email
    $mail->send();
} catch (Exception $e) {
    // Log the error or handle it accordingly
    echo 'Message could not be sent. Mailer Error: ' . $mail->ErrorInfo;
}
