How can PHP beginners prevent errors in their scripts that may prevent email delivery?

PHP beginners can prevent errors in their scripts that may prevent email delivery by ensuring they have correctly configured their email settings, properly sanitizing user input to prevent injection attacks, and handling errors gracefully to provide helpful feedback to users. One common mistake is not checking if the mail function returns true after attempting to send an email, which can help identify issues with email delivery. 

// Example of checking if the mail function returns true after sending an email
$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";
$headers = "From: sender@example.com";

if (mail($to, $subject, $message, $headers)) {
    echo "Email sent successfully!";
} else {
    echo "Email delivery failed. Please check your email settings.";
}
