The Twilio Difference
Carrier Route Optimization
A unique Feedback API lets Twilio monitor global routes to ensure messages always take the best path. See deliverability.
Messages sent to the same person automatically use a previous recognizable phone number to create a consistent experience and maintain conversation history.
Fall back to standard long-code phone numbers automatically in the US when a carrier is unable to receive messages from short codes.
