I'm not sure what you mean by "get sent mails list." Do you want to get a list of addresses to which the email was sent successfully?
If you are doing serious email campaigns, I usually recommend a third-party service that is in the business of sending emails. They can handle the bounces, the "spam" complaints, etc. You can export your list of subscriber to therm.
In addition to the DotNetNuke Newsletter module, there are also a couple of third-party (commercial) modules that you can use with DotNetNuke to do this, too. You'll find them at Snowcovered.
