SMS Consent & Opt-In Process
Last updated: April 27, 2026
Overview
BookMobile is a SaaS booking platform for mobile service businesses (auto detailing, pet grooming, mobile mechanics, etc.). Customers book appointments through an operator's public booking page at bookmobile.app/book/[operator-slug]. During the booking process, customers may opt in to receive SMS notifications about their appointment.
Opt-In Workflow
SMS consent is collected during Step 3 ("Your Details") of the booking flow. After selecting a service and choosing a date/time, customers enter their contact information. Below the phone number field, there is an unchecked checkbox that the customer must actively check to opt in to SMS messages. SMS is never sent unless the customer checks this box.
Email is required for every booking so that every customer receives booking confirmations, reschedule links, and reminders via email regardless of whether they opt in to SMS. SMS is strictly an additional convenience for customers who explicitly consent. No customer is ever left without a communication channel.
Booking Form — Step 3: Your Details
SMS Opt-In Checkbox (unchecked by default — customer must actively opt in)
Above shows the default state of the checkbox when a customer arrives at Step 3 of the booking form — empty and unselected. No SMS is ever sent unless the customer explicitly checks this box before submitting their booking.
Key points:
- The checkbox is ALWAYS unchecked by default — customers must ALWAYS actively opt in. The opt-in is NEVER pre-selected.
- SMS is only sent to customers who check the box
- The opt-in language includes clear disclosure of message types, rates, and how to opt out
- Links to our Privacy Policy and Terms are included directly in the consent text
Message Types & Frequency
Customers who opt in receive the following automated SMS messages:
- Booking confirmation — sent immediately after booking (1 message)
- Appointment reminder — sent 24 hours before the scheduled appointment (1 message)
Message frequency: Approximately 2 messages per booking.

Data Sharing
No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. All categories of personal information exclude text messaging originator opt-in data and consent — this information will not be shared with any third parties. Information sharing to subcontractors that directly support our service (Twilio for SMS delivery, Resend for email delivery, Supabase for data storage) is limited to what is necessary to deliver the messages you have consented to receive.
