What are the benefits of using Mailer classes in PHP for sending emails instead of raw text content?

Using Mailer classes in PHP for sending emails offers several benefits over sending raw text content. Mailer classes provide a more structured and organized way to handle email sending tasks, allowing for easier maintenance and scalability. Additionally, Mailer classes often come with built-in support for features like attachments, HTML content, and SMTP authentication, making it easier to send professional-looking emails with rich content. 

<?php
require 'vendor/autoload.php'; // Composer autoload

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

$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 = 'ssl';
    $mail->Port = 465;

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

    //Content
    $mail->isHTML(true);
    $mail->Subject = 'Test Email';
    $mail->Body = '<h1>Hello, this is a test email!</h1>';

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