You can easily download your contact lists as CSV files.

Enter Dashboard and open the module from where you want to download your contact list, i.e. either Media Center or the Screening Room. Click on Contacts in the left side menu and go to Backups tab.

Backup lists are displayed per date. Backups are done 4 times/day and the latest backup done to a date is the list that will be available for download. Download the list by clicking the download icon to the right, under Actions. 

Backup list contains contact details such as email address, name and company. You can also see what access group/s contacts belong too.
