How can PHP beginners ensure that their email content is displayed correctly in the email preview window?

When sending an email using PHP, beginners can ensure that their email content is displayed correctly in the email preview window by setting the appropriate MIME type and headers in the email message. This includes specifying the content type as text/html for HTML emails, setting the character encoding, and ensuring that the email content is properly formatted with HTML tags. 

<?php
$to = 'recipient@example.com';
$subject = 'Testing HTML Email';
$message = '<html><body><h1>Hello, this is a test email!</h1></body></html>';
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=utf-8' . "\r\n";

mail($to, $subject, $message, $headers);
?>
