E-mail has been one of the most convenient innovations of our time. It gives you the option to send a message in real time, and if there are problems with the mail delivery, you get a response that an error was encountered and that the sending of the e-mail failed. Gone are the days where you ponder if the mail has been received by the intended party. But sad to say, not everyone has embraced this technology. In conducting business transactions, people usually resort to the use of fax as a real-time means of communication. However, fax bills can be high if the call is overseas.
