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

When sending emails from a contact form in PHP, using a Mailer class can improve reliability by providing a structured and reusable way to send emails. The Mailer class can handle error checking, logging, and other necessary configurations to ensure that emails are sent successfully. This helps to prevent common issues such as emails getting stuck in the spam folder or not being delivered at all. 

// Include the Mailer class
require_once 'path/to/Mailer.php';

// Create a new instance of the Mailer class
$mailer = new Mailer();

// Set the email parameters
$mailer->setFrom('sender@example.com', 'Sender Name');
$mailer->setTo('recipient@example.com', 'Recipient Name');
$mailer->setSubject('Subject of the email');
$mailer->setBody('Body of the email');

// Send the email
if($mailer->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Failed to send email';
}
