What are the potential pitfalls of not properly handling email bounces in PHP?

If email bounces are not properly handled in PHP, it can lead to inaccurate email lists, decreased deliverability rates, and potential blacklisting of your domain. To solve this issue, you should implement a system to track and handle email bounces by updating your email list and removing invalid addresses. 

// Example PHP code snippet to handle email bounces

// Function to check if an email address is valid
function isValidEmail($email) {
    return filter_var($email, FILTER_VALIDATE_EMAIL);
}

// Check if email bounces and update email list
function handleBounce($email) {
    if (!isValidEmail($email)) {
        // Update email list to remove invalid email address
        // Code to remove email address from list
    }
}

// Example of handling email bounce
$email = "example@example.com";
handleBounce($email);
