Are there specific debugging techniques recommended for troubleshooting issues with PHPMailer not sending emails?

One common issue with PHPMailer not sending emails is misconfigured SMTP settings. To troubleshoot this, double-check the SMTP host, port, username, password, and encryption settings in your PHP code. Additionally, check for any errors in your email message content or recipient addresses that may be causing the email to fail. 

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

$mail = new PHPMailer(true);

try {
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->Port = 587;
    $mail->SMTPAuth = true;
    $mail->Username = 'your-email@example.com';
    $mail->Password = 'your-password';
    $mail->SMTPSecure = 'tls';

    $mail->setFrom('your-email@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');

    $mail->isHTML(true);
    $mail->Subject = 'Test Email';
    $mail->Body = 'This is a test email';

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