Received - An incoming message has been processed, and the message servicer has delivered the message to your number.

Undelivered - The message servicer has received a delivery receipt indicating that the message was not delivered. This can happen for a number of reasons including carrier content filtering (i.e. spam filtering), availability of the destination handset, etc.
