What are best practices for building HTML email templates with dynamic data in PHP?

When building HTML email templates with dynamic data in PHP, it is best practice to separate the HTML structure from the PHP logic by using a templating engine like Twig. This allows for easier maintenance and readability of the code. Additionally, make sure to properly sanitize and escape any user input to prevent XSS attacks. 

// Example using Twig templating engine
require_once 'vendor/autoload.php';

$loader = new \Twig\Loader\FilesystemLoader('path/to/templates');
$twig = new \Twig\Environment($loader);

$template = $twig->load('email_template.twig');
$data = [
    'name' => 'John Doe',
    'email' => 'johndoe@example.com',
    'message' => 'Hello, this is a test email!'
];

$html = $template->render($data);

// Send email using $html as the email body
