Using the list of privileged users who do not have emails here: https://phabricator.wikimedia.org/P74605## Summary
There are privileged user accounts who have not configured any email on their account. There is a risk with the new EmailAuth security measures that these important users may become locked out of their account, as the are unable to lookup the email authentication code.
We need to send each of these users a message notification asking them to configure an email address on their account.
