> They're also loved by bad actors who can leverage their service for fraud (search "toll fraud" if you're interested) and the ongoing effort and investment needed to counter this growing fraud problem is significant. And Twilio is wholly incompetent when it comes to battling this. Not only are they unable to keep bad actors off, they punish good actors. They require "approval" of what text messages you are going to send (never mind if part of it needs to be dynamic) and limit your sending ability to arbitrarily low levels. The company I work for just switched off them after high rejection rates and them randomly blocking us or limiting our send volume. They also bungled the whole number verification thing that recently went into effect, or at least dropped the ball on the communications side. Very glad to be off them and kind of sad, I remember when Twilio first hit the scene and it was truly amazing and so cool to work with.
