How can PHPMailer be implemented to send HTML emails successfully?

To send HTML emails successfully using PHPMailer, you need to set the `isHTML` property to true and include your HTML content in the body of the email. This allows PHPMailer to recognize the content as HTML and send it accordingly.

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

require 'vendor/autoload.php';

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

// Set the isHTML property to true
$mail->isHTML(true);

// Set the email content as HTML
$mail->Body = '<h1>Hello, this is an HTML email!</h1>';

// Add your email sending logic here
