What are the advantages of using a dedicated mailer class to handle HTML email generation in PHP applications?

When sending HTML emails in PHP applications, it is beneficial to use a dedicated mailer class to handle the generation of the email content. This helps to separate the email sending logic from the rest of the application, making the code cleaner and more maintainable. Additionally, a dedicated mailer class can provide functionalities such as template parsing, inline image embedding, and error handling, making it easier to send well-formatted and visually appealing emails. 

<?php

class Mailer {
    public function sendHtmlEmail($to, $subject, $htmlContent) {
        $headers = "MIME-Version: 1.0" . "\r\n";
        $headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
        $headers .= 'From: Your Name <your_email@example.com>' . "\r\n";
        
        return mail($to, $subject, $htmlContent, $headers);
    }
}

// Example usage
$mailer = new Mailer();
$to = 'recipient@example.com';
$subject = 'Test HTML Email';
$htmlContent = '<html><body><h1>Hello, World!</h1></body></html>';

if ($mailer->sendHtmlEmail($to, $subject, $htmlContent)) {
    echo 'Email sent successfully.';
} else {
    echo 'Email sending failed.';
}
