title: Extract mail list addresses from MailGun
body: <p>I want to extract the addresses OUT OF MailGun, into a CSV and delete the MailGun altogether.
  The MailGun database is the only copy of the 951 addresses I have absolutely no access to the database in any form other than looking at the list in MailGun. </p>
