When you find a listing in the Homesnap app that you would like to send to a customer, there is a simple way to share it with them. As you scroll down the listing (right after you get to the Property History section) a little bar will pop up at the bottom of your screen. Tap on the icon on the far right (it looks like a box with an arrow pointing out of the top):
You will then have several different options regarding sharing this listing- text, email, AirDrop (on iPhone), email, etc.
There is also an option at the bottom called Homesnap Messages, which is an in app messaging system that can have access to your phone's contacts.
