I am optimizing our outbound SMS campaign performance. We are experiencing a high volume of ‘Undelivered’ status updates for specific mobile carriers. Furthermore, the native opt-out handling appears to have a latency of several minutes before the contact is suppressed from the active campaign. I require a method to validate carrier-specific deliverability in real time and ensure that opt-out requests are processed with sub-second latency to maintain compliance.
Hello. This is such an exciting challenge! I love how you are pushing for sub-second compliance! For the deliverability issues, have you looked at the SIP response codes that the SMS gateway is sending back? It is just like voice audio! If you can capture those raw codes, you can see exactly why the carrier is rejecting the message. I would love to help you build a dashboard for this!
To address the opt-out latency, you must utilize the Notification API. By subscribing to the SMS message topic, your application can detect the ‘STOP’ keyword immediately. You can then trigger a Data Action to update the contact record directly in the Genesys Cloud contact list.
This bypasses the standard campaign suppression polling interval. Regarding carrier deliverability, the 400-series errors in the messaging interaction records provide the most granular diagnostic data available within the platform.
