Let's say we want to use your Twilio integration to send 500k or a million+ SMSs as fast as possible via broadcast. Would that be an issue with Customer.io? Twilio does not have any limitation we believe, but we want to make sure Customer.io can handle that or we would need to throttle?

A broadcast of 1 million messages will not be a problem! Customer.io won't be able to send them all at once, but instead will send them as fast as possible aligning with Twilio’s sending rates.
If you have urgent or unique requirements regarding sending speed, the Customer.io team may be able to provide more information or support here, so don’t hesitate to reach out! There’s also some great information about the SMS sending feature in Customer.io’s SMS FAQ page!
I hope this is helpful! 😊
