What are the best practices for handling automated email notifications in PHP to avoid spamming or overwhelming recipients?

To avoid spamming or overwhelming recipients with automated email notifications in PHP, it is important to implement proper throttling mechanisms, provide an option for users to opt-out or adjust notification settings, and ensure that the content of the emails is relevant and valuable to the recipient. 

// Example code for implementing throttling mechanism
$notificationLimit = 100; // Set a limit on the number of notifications to send per hour
$notificationCount = // Get the current count of notifications sent in the past hour from the database

if($notificationCount < $notificationLimit){
    // Send the email notification
    $notificationCount++;
    // Update the notification count in the database
} else {
    // Notify the admin or log the attempt to send over the limit
}
