Did you know that by adding a .mailtracking.com at the end of a recipient's email address, you can track if the email has been read, how many times, for how long and even if it has been forwarded and to whom ! Eg : When sending an email to james@abc.com, just change it to james@abc.com.mailtracking.com and that is all ! All tracking information is sent to your email address automatically as and when your email gets read or forwarded. These guys are just so cool ! You may also visit them at email tracking website.
