Good day, Team. The Sending Hours scheduling functionality is currently not restricting messages to within the configured selected time frame. Any messages sent to an application will be delivered immediately. Pause Sending does still work. If you have any queries, please send us an email to [email protected]. Thanks, Modica Support Team.

Our Developer team has resolved the issue affecting the Sending Hours Service. Over the weekend messages that should have been held within our systems due to the clients Sending Hours restrictions were not diverted to a queue and instead went out immediately. A fix was successfully implemented at 09:10 AEST (23:10 UTC) today. We are no longer seeing errors for this issue, we have also successfully tested the Sending Hours service, you should see your Sending Hours Windows being enforced correctly since 09:10 AEST We will continue to monitor the Sending Hours service until we have seen the correct handling of messages for Sending Hours users over an extended period of time. Regards Modica Support team
