What are recommended ways to structure PHP code for sending mass emails to avoid errors and improve performance?

When sending mass emails in PHP, it's important to structure your code efficiently to avoid errors and improve performance. One way to achieve this is by using batch processing, where you send emails in chunks rather than all at once. This helps prevent timeouts and memory issues that can occur when sending a large volume of emails. 

// Define the batch size for sending emails
$batchSize = 50;

// Loop through your email list and send emails in batches
for ($i = 0; $i < count($emailList); $i += $batchSize) {
    $batchEmails = array_slice($emailList, $i, $batchSize);

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