How does the code snippet provided handle the selection of individual users for newsletter delivery?

The code snippet provided does not handle the selection of individual users for newsletter delivery. To solve this issue, we can modify the code to include a query that selects individual users based on certain criteria, such as their subscription status or preferences. 

// Connect to the database
$connection = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($connection->connect_error) {
    die("Connection failed: " . $connection->connect_error);
}

// Select individual users for newsletter delivery
$sql = "SELECT * FROM users WHERE subscribed = 1";
$result = $connection->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        // Send newsletter to individual user
        sendNewsletter($row['email'], $newsletterContent);
    }
} else {
    echo "No subscribed users found for newsletter delivery.";
}

// Close database connection
$connection->close();
