When texts are available
Text messaging has to be enabled for your account before anything can be sent by text. Settings → Notifications tells you the current state: available, restricted to numbers you have verified, or not set up. Email notifications work either way.
Appointment texts and marketing texts
Appointment confirmations, reminders, cancellations, and reschedules are separate from marketing texts. A marketing text is a promotion, discount, announcement, or win-back. Marketing texts require the client's agreement. An appointment reminder opt-in is not marketing consent.
Consent and opting out
Customers can agree to marketing texts while booking, and messages explain how to stop. Someone who replies STOP stops receiving text messages and can still receive email.
Usage
Included SMS segments apply to the business account. They do not reset separately for each user or location. Pro includes 500 marketing segments a month. Team includes 1,500. The approved top-up is 500 segments for $10, and OperMae does not charge it automatically. Usage is shown under Settings → Billing.
Keep them short
The important details live in the email; the text is the nudge.
