// Include the PHPMailer library
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

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

// Read the content of the file
$fileContent = file_get_contents('path/to/file.html');

// Set the body of the email to the file content
