It doesn't seem possible to export unconfirmed subscriber data to a CSV file. Is that a deliberate choice on CM's part? For us, it would be helpful to be able to do that so we can see in excel which people have not clicked on the confirmed opt-in link, possibly because it has disappeared into junk or quarantine.
At the moment we have to paste the information in manually to excel: an export data option would be a little simpler.
You are correct that at this time you cannot export unconfirmed subscribers easily. The best you can do is change the count per page at the bottom to 100 and copy and paste the results into a spreadsheet. I have added the ability to export unconfirmed subscribers as a feature request for you.
