How can using a Mailer class in PHP improve the process of sending email messages?

Using a Mailer class in PHP can improve the process of sending email messages by encapsulating all the necessary functionality for sending emails into a reusable and modular class. This simplifies the codebase, promotes code reusability, and makes it easier to manage and maintain email sending functionality in a PHP application. 

<?php

class Mailer {
    public function sendEmail($to, $subject, $message) {
        // Code to send email using PHP's mail function or a third-party library
        // Example using PHP's mail function
        mail($to, $subject, $message);
    }
}

// Example usage
$mailer = new Mailer();
$mailer->sendEmail('recipient@example.com', 'Test Email', 'This is a test email message.');
