Images: ReadNotify's tracking service

This is a screenshot of the ReadNotify page that instructs users how to send a bugged e-mail. Users of the service register their e-mail addresses with ReadNotify and then simply append ".readnotify.com" to any e-mail address they send mail to if they wish the message to be tracked. Recipients won't see this, but could tell from the e-mail headers that the message was relayed.

ReadNotify also offers plug-ins for various e-mail clients, including Web-based e-mail, to make bugging a message easier.

ReadNotify.com offers a detailed report of what happens with tracked e-mail messages or documents. The report includes details on when, where, on what type of PC, and for how long the traced information was viewed. It even includes a small map of where the individual who opened the mail or file is likely located, based on the Internet Protocol address of the computer.

Additionally, if a message is forwarded, the report states the probable e-mail address of the individual it was sent on to. It also displays if a message is reopened by anyone.
