Get Notified When Your Email is Opened

Get Notified When Your Email is OpenedWhile surfing the web I found a great way by which you can track the emails you send.Now you can find out when your email has been read by the recipient. Now you need not to guess whether your email has been read or not. You can get a notification when your email has been opened. This facility is provided by many sites but most of them are not free.
