title: Twilio Copilot - Will Sticky Sender Create a Mapping If The First Message Is Received By One of My Numbers?
body: <p>When you are using Twilio Copilot, the service will create a mapping of which one of your numbers was used to send messages to a particular target phone number - and based on this mapping, always only send to the target phone number with the same Twilio phone number.</p>
  
  <p>Will Copilot do the same thing if the first message is sent by a target phone number to one of my Twilio numbers?  </p>
  
  <p>For example, if <code>123-456-7890</code> (number belonging to my customer) sends a message to <code>999-999-9999</code> (one of my Twilio phone numbers), I want to ensure that every message I send to this customer going forward originates from <code>999-999-9999</code> and not any of my other Twilio numbers.</p>
