SMS Opt-In
Last updated: October 8, 2026
This page describes how Guwy collects consent for SMS messaging, what messages clients receive, and how to opt out.
Guwy only sends messages to clients who have explicitly opted in. We never send unsolicited messages or sell your phone number.
How Clients Opt In
Clients provide consent to receive SMS messages through the following methods:
1. Online Appointment Booking
When a client books an appointment through a Guwy-powered booking page, they provide their phone number and check a consent checkbox that reads:
"I agree to receive appointment reminders and confirmations via SMS. Msg frequency varies. Msg & data rates may apply. Reply STOP to opt out. Messaging Policy · Privacy"
This checkbox is optional — clients can complete their booking without opting in to SMS. The booking page is publicly accessible and does not require login.
2. Business Registration
When a business owner creates a Guwy account, they can opt in to receive account-related SMS notifications by checking a consent checkbox during the registration process that reads:
"I agree to receive account notifications, payment reminders, and booking alerts via SMS from Guwy. Msg frequency varies. Msg & data rates may apply. Reply STOP to opt out at any time. Messaging Policy & Privacy Policy"
This checkbox is optional — business owners can register without opting in to SMS.
3. In-Person at the Business
When a business staff member creates an appointment on behalf of a walk-in or phone-call client, the client verbally consents to receive notifications. The staff member records this consent in the Guwy system.
What Messages Clients Receive
After opting in, clients may receive the following types of messages:
- Appointment reminders — e.g., "Hi Maria, reminder of your appointment at [Business Name] tomorrow at 2:00 PM."
- Booking confirmations — e.g., "Appointment confirmed! Your appointment is on March 15 at 2:00 PM."
- Consent form links — e.g., "You have a pending consent form for your upcoming appointment. Complete it here: [link]"
- Cancellation & rescheduling notices — e.g., "Your appointment has been rescheduled to March 17 at 3:00 PM."
Message Frequency
- Typical frequency: 1-3 messages per appointment (confirmation + reminder + consent form if applicable)
- Messages are only sent in relation to actual appointments or required forms
- No marketing messages are sent without separate explicit consent
- Message and data rates may apply
