Can someone help in writing a program for extracting the email ids from the contact list of a given google account?
Thanks in advance
This question should really be directed more towards Google support, as this side of your implementation involves their API, and we have no specialty to assist or troubleshoot issues with that. I did so some research and it seems that http://code.google.com/apis/contacts/ would be the best place to get started integrated with Google contacts. If you are having issues integrating the data you retrieved out of Google's API’s into Constant Contact, please let us know and I would be more than happy to assist you with this.
