How Customers Opt In

During the booking checkout flow on a business's widget powered by CTRL&BOOK, customers enter their contact details. To receive automated text updates, they must explicitly check the opt-in checkbox.

This checkbox is unchecked by default. Opt-in is completely voluntary, and customers can successfully complete their bookings without opting in to text notifications.

Illustration: consent form shown at checkout

This is an illustration using a placeholder business name, reproducing the phone input and unchecked SMS consent checkboxes presented to customers at the checkout step. On a live booking page the customer’s actual business is named in both disclosures, and each business has its own opt-in page at /booking/<business>/sms-opt-in.

I consent to receive non-marketing text messages from CTRL&BOOK about my bookings — confirmations, reminders, changes, and other service updates. Message frequency varies. Message and data rates may apply. Text HELP for assistance, reply STOP to opt out. Consent is not required to book. See our Terms and Privacy Policy.

SMS Message Flow & Policies

Message Content: We only send transaction-based text messages. These include booking confirmations, schedule reminders, rescheduling or cancellation notices, and alert notifications when a business replies to customer messages.

Separated senders:The shared CTRL&BOOK toll-free sender only sends locked booking notifications. Promotional texts use a business-specific dedicated sender only after separate marketing consent and A2P Mixed registration are verified. Tenant-written campaign content can never use the shared sender.

Opt-Out: Customers can text STOP, QUIT, UNSUBSCRIBE, or CANCEL at any time to opt out.

Opt-In Data Protection: All SMS opt-in consent and originator data are protected and strictly kept confidential. See our Privacy Policy for details.
