With the release of the SMS Billing Report, you can now keep track of the number of SMS and MMS messages you sent and received inside your Zaius account. You can compare the total number of messages to your subscription limit to determine whether you are still within the range of your subscription or if you will have to pay for overages.
You can navigate to this report by going into the App Directory, selecting the SMS app tile, switching to the Settings tab, and opening the Billing section.
You can select which month's metrics to view from the drop-down. For the current month, you will see a partial report.
Note that if you send to Canada, the table will display a separate row for it. We call these numbers out because there is a small surcharge for messaging outside the U.S.
