  • Higher message deliverability:
     For every Sender ID request, Twilio completes a rigorous due-diligence and registration process with the telecommunication carrier in that country. Once this process is completed, Twilio handles fluctuating telecom logic, regulations, and carrier-specific rules to ensure your A2P messages reach their destination
  • Improved brand recognition: 

     Because recipients see your name with every SMS sent, using a recognizable Alphanumeric Sender ID reinforces your branding.

  • Increased open rates:
     With Alphanumeric Sender IDs, recipients immediately recognize the sender and know the message is legitimate. As a  result, they are up to 80% more likely to open the message.
