Foonz, the group calling service, has added message confirmation to its services.
Now you can leave a message for an entire group and then get confirmation for your message delivery. You'll be able to see exactly who listened to your message. Great feature when you're the one leaving the message, right? As always, the service is free, other than your calling costs, and provides a business-like service for anyone to use. Foonz got $1.08M from Morgenthaler Ventures in its first round of funding early on this year.
