What is sent by text
Appointment confirmations, reminders and change notices can be sent by text when you have a mobile number for the customer and text messages are turned on under Settings → Notifications.
Consent
Customers agree to receive texts when booking, and every message explains how to stop. Anyone who replies STOP is opted out automatically and keeps receiving email instead.
Verification codes
Codes used to confirm your own phone number are always sent by text, regardless of these settings.
Keep them short
Texts are read in seconds. The important details live in the email; the text is the nudge.
