Customize Email Body

We are using this hook to customize the email body using PHP:

function custom_email_body_content($message, $data, $action_settings) {
    // You may want to check if the form needs to be customised here
    // $data contains information about the form that was submitted
    // Eg. if ($data[form_id]) === ...

    // Convert the submitted form data to an associative array
    $form_data = array();
    foreach ($data['fields'] as $key => $field) {
        $form_data[$field['key']] = $field['value'];
    }

    // Do something to the email body using the value of $form_data['zipcode']
    // Maybe a str_replace of a token, or generate a new email body from a template

    // Return the modified HTML email body
    return $message;
}

add_filter('ninja_forms_action_email_message', 'custom_email_body_content', 10, 3);

I can display a single field like the First Name without issues like so:

$f-name = $form_data['first_name'];

But this doesn’t work for checkbox lists. What’s the proper way to fetch checked values in a checkbox list field?
