What are some common pitfalls when using the PHP mail() function for sending newsletters?

One common pitfall when using the PHP mail() function for sending newsletters is that emails may end up in spam folders due to improper headers or content. To avoid this, ensure that your emails have proper headers, including a valid From address and a relevant subject line. Additionally, consider using a library like PHPMailer to handle sending emails, as it provides more robust features for sending HTML emails and attachments. 

// Example using PHPMailer library to send a newsletter

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');
    $mail->Subject = 'Your Newsletter Subject';
    $mail->msgHTML('<p>Your newsletter content goes here.</p>');

    $mail->send();
    echo 'Newsletter sent successfully';
} catch (Exception $e) {
    echo 'Error sending newsletter: ' . $mail->ErrorInfo;
}
