What potential issues could arise when using PHPMailer to send emails, as seen in the provided code snippet?

One potential issue that could arise when using PHPMailer to send emails is the lack of error handling for failed email deliveries. To address this, you can implement error checking to capture any exceptions thrown during the email sending process and handle them accordingly. 

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

$mail = new PHPMailer(true);

try {
    // Attempt to send the email
    $mail->send();
    echo 'Email sent successfully';
} catch (Exception $e) {
    echo 'An error occurred: ' . $mail->ErrorInfo;
}
