Sharing a Nudge‎ > ‎

Can I email contacts I have in Gmail, Yahoo, etc.?

Yes!  You can email contacts in Gmail, Yahoo, Hotmail/MSN, AOL, and your Mac OSX address book.
On the “deliver” tab above your Nudge, find the “Add contacts from google, yahoo, aol and more” and click that.  From there, you just need to login to your email client account and follow the steps as it walks you through the process.
