Are there specific limitations on free web hosting providers that prevent PHPMailer from functioning properly?

Some free web hosting providers may have restrictions on sending emails using PHPMailer due to security concerns or limitations on server resources. To solve this issue, you can try using SMTP authentication with a valid email account from the hosting provider or check if the hosting provider allows sending emails through their SMTP server. 

// Example PHP code snippet using SMTP authentication with PHPMailer
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

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

    $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 sent using PHPMailer';

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