What are some best practices for creating a newsletter distribution system using PHP?

When creating a newsletter distribution system using PHP, it is important to ensure that the system is efficient, secure, and user-friendly. One best practice is to use a database to store subscriber information and preferences, allowing for targeted and personalized newsletters. Additionally, implementing a double opt-in process can help prevent spam and ensure that subscribers are genuinely interested in receiving the newsletters. 

// Sample PHP code for creating a newsletter distribution system

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "newsletter_system";

$conn = new mysqli($servername, $username, $password, $dbname);

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

// Code for adding a subscriber to the database
$email = $_POST['email'];
$subscribe_date = date('Y-m-d H:i:s');

$sql = "INSERT INTO subscribers (email, subscribe_date) VALUES ('$email', '$subscribe_date')";

if ($conn->query($sql) === TRUE) {
    echo "Subscriber added successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
