What are the drawbacks of using automatic redirection in HTML emails for PHP newsletters?

Using automatic redirection in HTML emails for PHP newsletters can be problematic because it can trigger spam filters and cause the email to be marked as suspicious. To solve this issue, it is recommended to avoid using automatic redirection and instead include clear call-to-action buttons or links for the user to click on. 

// Example PHP code snippet without automatic redirection in HTML email

// Create HTML email content with a call-to-action button
$emailContent = "
<html>
<body>
<h1>Welcome to our Newsletter!</h1>
<p>Click the button below to read the latest news.</p>
<a href='https://www.example.com/newsletter'>Read Now</a>
</body>
</html>
";

// Send the HTML email
mail($to, $subject, $emailContent, $headers);
