A method of correlating outgoing electronic communications with received electronic messages includes: sending an electronic message associated with a second party to a first party; subsequently receiving an outgoing electronic communication from the first party by the second party; automatically determining whether the outgoing electronic communication resulted from the electronic message, based on electronically stored information about the sending of the electronic message and about the subsequently received outgoing electronic communication; and if it is determined that the outgoing electronic communication resulted from the electronic message, flagging the outgoing electronic communication to have a different status from outgoing electronic communications not determined to have resulted from an electronic message.
