What are some common pitfalls to avoid when using PHP scripts to send mass emails?

One common pitfall to avoid when sending mass emails with PHP scripts is not properly handling errors and exceptions. It's important to implement error handling to catch any issues that may arise during the email sending process, such as network errors or invalid email addresses. Additionally, make sure to use a proper email library or service to send mass emails efficiently and securely. 

// Example of implementing error handling when sending mass emails
try {
    // Your code to send mass emails here
} catch (Exception $e) {
    // Handle any errors that occur during the email sending process
    echo 'An error occurred: ' . $e->getMessage();
}
