ability addresses admin considering contain customers download email emails groups logs newsletter ourself pay product seller service signing updates

I am considering signing up for this service. Will I have the ability to download all my customers email addresses to include them in my newsletter or product updates? I see that I can pay you to do it by groups but I don't need to do that as we are already set up to do it ourself. However I need to be able to download all the email addresses.

You can download the logs from E-junkie seller admin. They contain the emails.
