FreshBuzzer offers text and email notifications for up to 3 recipients when your guest checks in.

The notification will be sent when they use their code for the first time (or receive the first buzzer call) and not for any subsequent events.

Please note that this only means they arrived to the building and their front door access worked. It does not guarantee that they were able to find their way to the unit, take the elevator to the right floor, unlock the smart lock etc.
