When you integrate your Google accounts such as Gmail and Google Calendar, Clay is able to see the emails you're interacting with, but we don't have permission to pull additional info from Google Contacts. Additionally, Google Contacts oftentimes has faulty data that would make Clay more cluttered and inaccurate.
With that being said, if your data is clean and you want it in Clay, we're happy to manually import it. If you export your Google Contacts as a CSV or V-card file and email it to us, we'll make sure that information gets into Clay, notes, and groups intact.
