What are some potential pitfalls when using PHPMailer for sending emails via SMTP?

One potential pitfall when using PHPMailer for sending emails via SMTP is not properly handling errors or exceptions that may occur during the email sending process. To solve this issue, it is important to implement error handling to catch any potential errors and handle them appropriately. 

use PHPMailer\PHPMailer\Exception;

$mail = new PHPMailer(true);

try {
    // Code for setting up PHPMailer and sending email

} catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: ' . $mail->ErrorInfo;
}
