How to determine number of emails to send

I have a running email queue processed by cron task mautic:emails:send. Cron task is running for two days. Some emails have already been sent but I don’t know how can I check number of emails remaining to send. Is there any console task to show statistics or something? GUI shows me that 100% of messages was send but when I list app/spool/default directory I see more than 2 millions of files left.
