Between 1 AM and 6 AM UTC, we sent out a batch of email notifications to some customers during an internal import. These notifications were from old public posts on our Zendesk Help Center. We apologize for this error; you can safely delete those email notifications.
On Friday, May 28, 2021, we migrated some public articles and comments from our support.zendesk.com instance to prepare for changes we’re making to our internal Zendesk instance to better support our customers. Unfortunately, this triggered extraneous emails to some end-users between 00:42 AM UTC and 05:04 UTC. The issue was caused by a misconfiguration of a dataset migration where the `notify_subscribers` flag was not set to disabled. This issue has been remediated and no additional notifications will be sent.
