1. A method of monitoring events associated with the transmission of an electronic mail message comprising the steps of:

  • transmitting electronic mail messages to a plurality of recipients,wherein each of the mail messages has an identifier code contained within the mail message;

    directing a recipient of a mail message to an intermediate response server and thereafter creating a link between the recipient and a destination site;

    temporarily storing a received identifier code in a buffer;

    storing in a bitmap after a predetermined period of time information which provides a correlation between the identifier code and the act of creating the link, including generating the logical “

    or”

    of the identifier code and a location in the bitmap; and

    dynamically sizing the bitmap to be sufficiently large to accommodate the storage of a largest received identifier code.
