I have Dux-Soup Pro, do I still need points to capture emails?

Yes, the points are required to capture the emails of your 2nd and 3rd-degree connections.

Once you upgrade to a Pro Dux-Soup account, you have the access to all features like scanning profiles, downloading data, sending connection requests, etc. 

Please note that Dux-Soup is able to capture the email addresses only for 1st-degree Linkedin connections (you do not need points for this). If you want to capture the emails for your 2nd and 3rd-degree connections, you will have to purchase Dux-Soup Points in addition to the Pro subscription.
