Sticky Sender makes sure the same “From” number is selected every time your application sends a message to a particular recipient. Your application will consistently sned messages to your end user from a signle recognizable phone number. Once this feature is enabled, Telnyx will maintain a mapping of the “To” and “From” numbers after the first message is sent to a particular recipient, and 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.
