# SMS alerts and consent

> How LobbyStack collects consent for outbound appointment and workspace alert SMS.

LobbyStack uses one toll-free SMS number for outbound, non-marketing account notifications.

This number sends:

* Appointment confirmations and reminders to customers.
* Workspace alerts to verified operators.

This number does not send marketing, promotions, age-gated content, AI SMS replies, or manual SMS conversations.

## Consent model

LobbyStack collects SMS consent before sending alerts.

Appointment customers and operators use the same toll-free number, but they consent in different places.

### Appointment customers

When a customer books by phone, the AI receptionist asks for verbal SMS consent before sending an appointment confirmation or reminder.

The disclosure is:

> Can I text this number with your appointment confirmation and reminder? Message and data rates may apply. Reply STOP to opt out or HELP for help.

If the caller says yes, LobbyStack records the opt-in and sends appointment SMS for that phone number.

If the caller says no, the appointment is still booked and no appointment SMS is sent.

### Operators

Operators are verified workspace users.

Before operator workspace alerts are sent by SMS, the operator must enable SMS alerts in **Settings** > **Notifications** and accept the SMS disclosure in the dashboard.

The operator disclosure is:

> I agree to receive SMS alerts from LobbyStack about missed calls, new messages, appointment activity, and workspace notifications at my verified phone number. Message frequency varies. Msg & data rates may apply. Reply STOP to opt out or HELP for help. SMS alerts are optional.

Operators can disable SMS alerts later in notification settings.

## Example messages

Appointment confirmation:

> Example Business: Your haircut appointment is confirmed for May 24 at 2:00 PM. Msg & data rates may apply. Reply STOP to opt out or HELP for help.

Operator alert:

> LobbyStack: New voice message for Example Business. Open your dashboard to review. Msg & data rates may apply. Reply STOP to opt out or HELP for help.
