Ready to upgrade your customer support?

This depends on the specific content of the message and the country you're in. In general, we recommend some kind of opt-in or guidance that a customer may be contacted via SMS before sending them customer support messages. We also recommend allowing customers to opt-out via texting a single stop-word—with Telnyx, this is built in automatically.
