An update deployed over the weekend resulted in issues tracking the status of emails sent through one of our communication providers. All impacted emails will have shown up in a "processing" state despite having been sent. When we were alerted of this error, we attempted to re-deliver all emails which were believed to be stuck in the processing state, however later discovered that these in fact had already been sent out, and the issue was tracking related.
All emails are now being routed via the email provider which was not impacted by this issue. Some customers may have received duplicate copies of emails from the last 3 days in the last hour (1-2x). No further duplicate emails will be received, and we're working on a fix to ensure this does not happen again.
