Last Friday, the network's engineering team resolved an issue that was affecting broadcast emails and email notifications on this Quilt With Us platform. One of the servers was not sending messages properly, and after restarting the server, messages dating back several days were queued for delivery. It took a few days before the backlog of unsent messages were finally delivered over the course of this past weekend. During this time, there was some duplication of messages and significant delays in receiving messages. So it looks like this issue is fixed.
At present, all email notifications and broadcast messages are being sent out as expected. If you're still seeing any issues, please let us know!
