The whole promise of LocusFounder is that you can run a business from your phone over text, before you even make an account. That only works if iMessage feels native, not like an SMS bot. SendBlue let us send and receive real iMessages programmatically, with SMS as a clean fallback, so the agent shows up as a normal blue-bubble conversation instead of a clunky shortcode. It's the piece that makes "just text it an idea" actually feel human.
