StateSending
// StatePending indicates a message waiting to be sent.
StatePending
// StateSent means the message has been sent completely, but may not
// have been delivered (or delivery confirmation is not supported.). For
// example, an SMS on the carrier network (but not device) or a voice call
// that rang but got `no-answer`.
StateSent
// StateDelivered means the message is completed and was received
// by the end device. SMS delivery confirmation, or a voice call was
// completed (including if it was voice mail).
StateDelivered
// StateRead means the message was read by the recipient.
StateRead
// StateFailedTemp should be set when a message was not sent (no SMS or ringing phone)
// but a subsequent try later may succeed. (e.g. voice call with busy signal).
StateFailedTemp
// StateFailedPerm should be set when a message was not sent (no SMS or ringing phone)
// but a subsequent attempt will not be expected to succeed. For messages that fail due to
// invalid config, they should set this state, as without manual intervention, a retry
// will also fail.
StateFailedPerm
// StateBundled indicates that the message has been bundled into another message.
