Improve Delivery

  • The Twilio Difference
  • MMS

    Create visual customer experiences with attachments and picture messages. Images are resized to meet carrier specs or sent as a link outside the U.S. and Canada.

  • Carrier Route Optimization

    A unique Feedback API lets Twilio monitor global routes to ensure messages always take the best path. See deliverability.

  • Sticky Sender

    Messages sent to the same person automatically use a previous recognizable phone number to create a consistent experience and maintain conversation history.

  • Reroute

    Fall back to standard long-code phone numbers automatically in the US when a carrier is unable to receive messages from short codes.

Scale as You Grow

  • Essential SMS Features
  • Queuing

    Send SMS as fast as you like. Twilio automatically queues and sends each message at a rate that keeps you compliant.

  • Multi-tenancy

    Use Subaccounts to share applications securely while keeping separate phone numbers, billing plans, configuration, and logs for each customer.

  • All character sets (Unicode)

    Exchange messages in every language and emoji. Only Twilio encodes Unicode characters for you without requiring custom code. See how Twilio compares.
