Additionally, original messages may result in received response messages (for example, a customer may elect to reply to a received message from the agent). Both these outbound and received responses will be linked to the original message. Original messages are identified by the lack of a message-generated tracking number in the received message subject header.

Outbound Message

A message sent by the agent to either a customer or an SME. Replies are outbound messages providing customers with either the answer to the their question (see Reply) or a status update. Outbound messages to SMEs are requests for information.

A tracking number is followed by a four-digit suffix as a site identifier (for example, TRK # 12345678-1000). The messaging software uses the tracking number to handle messages. An agent can use tracking numbers to find specific messages by searching on a message's tracking number. A customer could use a tracking number to reference an email correspondence.
