What are some alternative methods for sending newsletters in PHP that may improve performance?

Sending newsletters in PHP can be resource-intensive, especially when sending to a large number of subscribers. One way to improve performance is to use a third-party email delivery service like SendGrid or Amazon SES, which can handle the sending process more efficiently. Another approach is to batch the sending of emails in smaller chunks to avoid overloading the server and potentially getting flagged as spam. 

// Example of sending newsletters in batches using PHP

// Define the list of subscribers
$subscribers = array('email1@example.com', 'email2@example.com', 'email3@example.com');

// Set the batch size
$batchSize = 100;

// Loop through subscribers in batches
for ($i = 0; $i < count($subscribers); $i += $batchSize) {
    $batch = array_slice($subscribers, $i, $batchSize);

    // Send emails to subscribers in the current batch
    foreach ($batch as $subscriber) {
        // Code to send email to $subscriber
    }
}
