A first set of data related to one or more message senders is obtained from a first source, such as an email sever or email gateway. Each message sender has sent one or more electronic messages. A second set of data related to the one or more message senders is obtained from a second source. Message volume information that describes the messages sent by the one or more message senders for a period of time is determined based on the first set of data and the second set of data.
