SMS Terms & Consent
Last updated: June 18, 2026
SendLynx is a booking platform for local service businesses (barbers, salons, spas, trainers, cleaners, and similar). When a business enables text messaging, SendLynx sends that business's clients appointment-related text messages on the business's behalf, using our messaging provider, Twilio.
How clients opt in
Consent to receive text messages is collected on the business's public booking page, while the client is booking an appointment. At the contact-details step the client may check a clearly labeled SMS consent box. The box is unchecked by default; checking it is an explicit, affirmative opt-in. Texting is never required to book, and consent is never assumed from booking alone.
The consent box presents the following disclosure to the client:
“Text me appointment confirmations & reminders at the number above. By checking this box you agree to receive appointment-related texts from [Business Name] (via SendLynx). Message frequency varies (typically 1–3 per appointment). Msg & data rates may apply. Reply HELP for help, STOP to cancel.” with links to these Terms and our Privacy Policy.
The client must also enter their mobile number in the same form. Consent applies only to the specific business the client is booking with.
What messages we send
Messages are transactional and tied to a specific appointment: a booking confirmation when the appointment is made, and reminders before the appointment (typically 24 hours and 2 hours prior). We do not send marketing or promotional text messages through this consent.
Message frequency
Frequency varies by how often a client books, but is typically 1–3 messages per appointment (a confirmation plus reminders).
Cost
Message and data rates may apply, depending on the client's mobile carrier and plan.
Opting out and help
A client can reply STOP to any message at any time to immediately stop all further texts; we confirm the opt-out and send nothing further. Reply HELP for help, or contact the business directly. A client can opt back in at any time by checking the consent box again on a future booking.
Privacy
Mobile phone numbers and SMS consent are used only to deliver the appointment messages a client opted into. We do not share mobile phone numbers or SMS consent with third parties or affiliates for marketing or promotional purposes. See our Privacy Policy for how we handle data generally.
