Are there specific considerations or limitations when using PHPmailer to send HTML-formatted emails with complex content structures?

When using PHPmailer to send HTML-formatted emails with complex content structures, it's important to ensure that the HTML code is properly formatted and valid. Additionally, consider the email client compatibility for rendering complex content structures. To address these issues, make sure to thoroughly test the email template across various email clients and devices to ensure proper rendering. 

// Example PHP code snippet using PHPmailer to send HTML-formatted emails with complex content structures

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

// Include PHPMailer autoload file
require 'vendor/autoload.php';

// Create a new PHPMailer instance
$mail = new PHPMailer(true);

try {
    // Server settings
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'your@example.com';
    $mail->Password = 'yourpassword';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;

    // Recipient
    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');

    // Content
    $mail->isHTML(true);
    $mail->Subject = 'Subject of the email';
    $mail->Body = file_get_contents('email_template.html'); // Load HTML content from a file

    // Send the email
    $mail->send();
    echo 'Email has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
