The Delivery Panel on the System/Status page has an entry labeled "Sending statistics". And it says, "Not enough data available." I have been using Newsletter for nine months now and have sent out hundreds of automated newsletters.
So, my question is, what does it take to generate enough data to be able to see these mysterious statistics? I cannot find this mentioned anywhere in the documentation.
Hi, those "report" is a diagnostic report, probably the data cannot be stored or has been deleted. Try to use the reset button to restore the dataset and then it should start to collect delivery stats once again.
