Please allow me to export IP addresses!
I currently have to go into each client's screen to cut and paste the email address into an excel document so I can search through our logs to find out how they found out website.
Both the originating and most recent IP address are included in client exports.
We'd like to use IP addresses to create a geographical profile of where list members are located. This would then allow us to provide offers based on locations. Of course, using IP addresses isn't perfect, but it would be better data than no data in identifying groups of clients. We don't require addresses for people joining our lists.
Aweber has a feature that segments the list based on IP address and also creates maps. It would be useful in our 1SC endeavors.
