How can using a Mailer class improve the reliability of sending emails in PHP?

Using a Mailer class can improve the reliability of sending emails in PHP by encapsulating the email sending functionality into a separate class. This helps in organizing the code, making it easier to manage and maintain. Additionally, a Mailer class can handle error checking, logging, and retry mechanisms to ensure that emails are sent successfully. 

class Mailer {
    public function sendEmail($to, $subject, $message) {
        // Code to send email using PHP's mail function or a third-party library
        // Add error handling, logging, and retry mechanisms here
    }
}

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