Try Twilio
Our recommended link
SMS is the highest open-rate channel in the stack. Twilio is how it gets sent.
Inside GHL, SMS was built in but I was paying GHL's markup on every message. With Twilio direct, I pay the carrier rate. The saving per message is small - the saving at scale adds up.
Why Not a Simpler SMS Tool
Most SMS tools have monthly fees and lock you into their platform. Twilio is infrastructure - it does not try to be anything else. Claude is the layer that makes it intelligent. That separation is the point of the sovereign stack.
