RESOLVED 2 days ago - at 09/12/2025 03:02PM

Since the last update on September 11th, we have seen that all the new events for delivered, opened, etc have been correctly processed as they come. GIven this, we'll consider this issue resolved.

MONITORING 2 days ago - at 09/12/2025 01:03AM

We have finished processing all the events from September 10th to 11th and the processing queue has now caught up with the present time.

We also recalculated all the stats for the broadcasts delivered in the period.
We'll continue monitoring over the next 10-12 hours before considering this issue resolved.

IDENTIFIED 2 days ago - at 09/11/2025 10:12PM

We are still processing the list of events from September 10th - September 11th (missing 1/3 as of now).
Some broadcasts and emails might show up as "overdelivered" or with wrong stats since we are processing all the events, including some that may have been processed through the old behavior, which will be decommissioned when the queue catches up.

All the stats for broadcasts delivered since September 10th will be recalculated at the end of this process to eliminate any duplication.

IDENTIFIED 3 days ago - at 09/11/2025 06:33PM

We have identified what caused email events (delivered, opened, etc) to not be processed. We will be able to restore all the events from September 10th afternoon EST, though it will take some time until we catch up and be able to process all events coming live.
Until this is fixed, you will still see some stats missing due to the queue mentioned above.
