Supported Countries and SMS Rules

In the United States, reminders arrive from a phone number. Recipients can use keyword-based opt-out flows like STOP, and Etisia's privacy policy says opt-out requests are processed immediately. Keep expectations conservative here: Etisia does not provide a conversational inbox or reply-based rescheduling workflow.

By default, reminders in Australia and Austria arrive from a phone number, one the SMS provider assigns, with your business name at the start of the text. Both countries only allow registered sender names, so Etisia does not send from a name there. A client can text back, but no one reads the reply, neither you nor Etisia: cancelling goes through the link in the message, if you switch it on.

By default, reminders in these markets appear from a sender name rather than a numeric phone number. That looks cleaner from a branding perspective, but it also means normal text replies are not supported. Clients cannot cancel or opt out by replying to that sender; if you enabled the cancel link, they can cancel through that link instead.

Different sender types, same job: get the reminder in front of the client in a usable format.

This is a common operational worry, especially for businesses that book manually or see clients from different countries. Etisia normalizes local number formats into a valid deliverable format before send. You should not need to manually rewrite every number with a country code.

If your country is not listed above: contact support with your country and estimated monthly SMS volume, ask whether support is live, in rollout, or not yet available, and use the answer to decide whether to start a trial now or wait.
