  1. identified Sep 09, 2025, 06:18 PM UTC

    Some inbound customers are reporting delays and deferrals on receiving mail. We have identified the cause and are working on a resolution.

    A fix has been shipped and we are monitoring results.

  3. monitoring Sep 10, 2025, 03:06 PM UTC

    while we released a fix last night, some customers continue to report missing mail log statuses from Monday 9/8 to Tuesday 9/9 - we are still reviewing these reports

  4. resolved Sep 10, 2025, 07:23 PM UTC

    After thorough investigation we found: - A new log entry was added each time a piece of mail was deferred - “No Delivery Status Found” mail log rows didn’t get updated when the email was later delivered - Instead, a brand new mail log entry with the “Delivered” status was written
