Is there a way for me to sync email addresses I have in OSX address book or that I've synced to Google Contacts to a list in Campaign Monitor? My contact list is very fluid. Updating it in both places is a real pain.
There isn't any built in way to keep them synced - we do have an API, but that is more intend for integrating with different systems like blogs, CMS tools etc.
Also, be aware that uploading your whole address book is often not going to meet our permission requirements ( http://www.campaignmonitor.com/resources/entry/558/about-permission/ )
Hey randomly_handsome, we now integrate with Google Contacts, thanks to OneSaas.
OneSaas is a web service that allows multiple web apps/APIs to communicate together. What's best is that it can push your contacts from Highrise, Basecamp, Freshbooks and more to a Campaign Monitor subscriber list. We've got a in-depth walkthrough in our blog.
