Messaging Copilot is a tool designed to help Twilio customers scale their messaging applications by providing a global routing and delivery system that automatically selects the best number to send a message based on delivery goals. The tool offers three key features: Geo-Match, which uses local numbers in different countries; Sticky Sender, which enables users to associate a business with one number; and Scaler, which intelligently distributes traffic across multiple numbers to reach large audiences. Messaging Copilot consists of two components: a designated group of phone numbers (number pool) and delivery options, allowing customers to easily route their messages without needing additional software logic or engineering resources.
