What are some best practices for setting up header descriptions when sending HTML emails with PHP mail()?

When sending HTML emails with PHP mail(), it is important to set up header descriptions properly to ensure the email is displayed correctly in the recipient's inbox. One best practice is to include a Content-Type header with the value "text/html" to indicate that the email content is in HTML format. Additionally, setting the charset to UTF-8 can help ensure that special characters are displayed correctly. 

// Set up email headers
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";

// Send email
mail($to, $subject, $message, $headers);
