Engineered for Reliability
A lot has to go right for the SMS you send to reach its destination. It starts with picking the best phone number and then requires navigating a global ecosystem of carriers. Twilio has built intelligent cloud software to handle it all for you.

The kinds of problems we were seeing with other providers, we just haven’t seen with Twilio. I sleep easier, and my engineers sleep easier.

Designed for Developers
Build your app without the hassle of creating compliance logic for global telecom regulations or writing custom code for every SMS corner case. Twilio navigates the fragmented world of mobile carriers for you, so your SMS always arrives intact.
  • Tools to build faster

    Use Twilio helper libraries, monitoring and debugging tools, documentation and support services. Everything you need to get your app to market quicker and keep you from getting stuck. Or quickly get you unstuck.

  • Sender intelligence

    Send messages from a pool of phone numbers to speed delivery or use the same local number to maintain a conversation. We handle the backend logic for you.

  • Content intelligence

    Ensure your SMS and MMS messages arrive the way you intended. Different devices and carriers don't always treat content the same. Twilio handles these differences with image transcoding, character encoding, and message assembly.

  • Compliance built-in

    Stay compliant with global SMS carrier regulations. Twilio handles it for you, from managing SMS volume to maintaining your blacklisted phone numbers.

No other vendor had the simplicity of APIs or the reputation for handling large-scale consumer services.
