In what scenarios would using PHP's mail() function be more advantageous than relying on external form mailers for sending confirmation emails?

Using PHP's mail() function may be more advantageous than relying on external form mailers when you want a simple and lightweight solution for sending confirmation emails directly from your server without the need for additional dependencies. This can be useful for smaller projects or when you have more control over the server environment. 

$to = "recipient@example.com";
$subject = "Confirmation Email";
$message = "This is a confirmation email.";
$headers = "From: sender@example.com";

// Send the email
if(mail($to, $subject, $message, $headers)) {
    echo "Email sent successfully.";
} else {
    echo "Email sending failed.";
}
