Been using Keila to send emails to members of an employee group. We've had great success sending monthly newsletters and occasional email updates about important events coming up.

As a quality assurance measure, my personal email is subscribed to the lists so that I can receive emails and view them as a recipient.

About a week ago, a member can expressed concern about no longer receiving the emails and not sure why. I looked and this member had been unsubscribed from the mailer. So I deleted their contact and re-added them to the contacts lists. But after the next email they were again unsubscribed. (Not sure how to add them again or fix this.)

I know that this must be a glitch of some kind, be cause just today MY personal email was unsubscribed and I know that I did not unsubscribe. What is causing this and how can I fix?
