Bug: Undefined variable: delid on WordPress dashboard

With define('WP_DEBUG', true); in wp-config.php an error can be observed on WordPress dashboard in WP Email Capture metabox:

Notice: Undefined variable: delid in /../wp-content/plugins/wp-email-capture/inc/tabledata.php on line 46

Wrong:

if ($limit == 0) {
$delid = wp_email_capture_formdelete($result->id, $result->email);
}

Suggested fix:

if ($limit == 0) {
$delid = wp_email_capture_formdelete($result->id, $result->email);
} else {
$delid = '';
}

General note: Please check the whole plugin for these kind of bugs, I showed the free Lite version to a customer who wanted to buy an email capture plugin but then all these notices appeared when they tested on dev-server and scared them away from the plugin, too bad.
