8. What does “Rejected” Delivery status mean?

The “Rejected” delivery status happens when the messages are not delivered by the carriers due to Number Blockage or Velocity Block of Numbers. Most carriers prefer to use regulations to control the flow of spam. In developing markets, however, technology is used to filter out unwanted texts and velocity. These filters will send back “Rejected” status if the message is undelivered due to Spam Filtering.
