I need a way to know when a particular list I have was used last and for which email send. Is there a report somewhere that I am missing that would show me some statistics about a list such as the number of times it has been used, the last used date and last used email send?
There isn't a report available like this right now but this is a good idea for the future! You can only see the lists you sent to in the individual schedule page for each email at this time.
