On the evening of 3/29 between approximately 8pm - 9:30pm eastern time (ET), AOL suffered a technical issue where every email sent to them received a "recipient address rejected" reply. This means any deployments actively attempting deliveries in that time frame may have caused valid AOL (and affiliated domain) addresses to be flagged invalid for future campaigns. Epsilon is currently working to identify any such addresses that may have been incorrectly “bounced out” in that time frame and restore these records to their proper state for any clients using our DREAM, DREAMmail, or Harmony platforms. If you have any questions please contact your account team. If you are using an Email Service Provider (ESP) other than Epsilon, we recommend you consult with your provider to ensure they have evaluated the impact on any of your campaigns during this time and have made necessary adjustments to any email addresses who were opted out due to this issue.
