Greetings Twilio Team. Below is the method through which our clients provide consent to receive text communications. This is a screenshot of our Zoho Bookings page through which our clients book their appointments. Of course, if they prefer not to receive these messages, they may opt out any time. This agreement must be made before they can book their appointment with us. We do not use text messages for advertising/promotional purposes. They are only sent to existing clients who have specifically opted in.
