 * My client is using this plugin to notify 2k users when new documents are uploaded
   but it seems to be triggering WP Engine security with how it’s looping the user
   accounts. It worked previously but we are now getting an error in the logs “attempting
   to enumerate users” and it fails to send. It appears the first few may have gone
   out before this failed.

 * This error may actually be a red herring. I think the real culprit is the high
   number of emails we are trying to send out and WP Cron timing out.
