Should I be able to aquire emails of feedburner people?

I’m not exactly using the feedburner plugin – I dropped the code into my page(s) that I got from the google/feedburner interface.

What I’m wondering is how do I see the peoples email addresses that have signed up. I can see that folks have signed up in the csv file you can download (again from the google/feedburner pages). But all it contains is what day and how many people signed up. Is this normal?

If there is simply no way to ‘gather’ these people’s emails, then can someone recommend a plugin that does what feedburner does, but also collects emails?

Thank you so much!
