Are there any recommended PHP libraries or resources for sending HTML emails that can help avoid formatting issues?

When sending HTML emails using PHP, it's important to use a library that handles the formatting correctly to avoid common issues such as broken layouts or missing styles. One recommended library for sending HTML emails in PHP is PHPMailer, which provides a simple and reliable way to send HTML emails with proper formatting.

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

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

// Set up the email parameters
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Subject of the email';
$mail->Body = '<h1>This is the HTML content of the email</h1>';

// Add recipient email address
$mail->addAddress('recipient@example.com', 'Recipient Name');

// Send the email
if ($mail->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Email could not be sent.';
}
