Sticky Sendersticky-sender

Sticky Sender makes sure the same “From” number is selected every time your application sends a message to a particular recipient. This allows your application to consistently send messages to your user from a single recognizable phone number. When Sticky Sender is enabled, Telnyx will maintain a mapping of the “To” and “From” numbers. This mapping is created after the first message is sent to a particular recipient. Any future messages to that recipient will use the same “From” number.

If Sticky Sender is turned off, Telnyx will disregard previously established "To" and "From" mappings when selecting the "From" number for new messages. When a Telnyx phone number is removed from your profile, all associated Sticky Sender mappings are removed.

To configure Sticky Sender in your Portal:

  1. 1Click on “Messaging” in the navigation menu on the left-hand side of the Telnyx Mission Control Portal.
  2. 2Click the edit symbol next to the Messaging Profile you want to use.
  3. 3Under Outbound, toggle on “Number Pool” to enable.
  4. 4Select the “Sticky Sender” checkbox.
  5. 5Click “Save”.
