Hi Sherry,

This is an excellent question, thank you for asking. It is possible to record a message on your NationBuilder phone number, but it is not possible to have that number robocall your constituents with your message. However this does not mean that you are not able to perform robocalls using NationBuilder; we have a number of partners that offer a robocall function and integrate with our API they are NotifyNow and CallFire. You can learn more about setting up your phone number and configuring voicemail here.
