When you need to send a short message to someone quickly and get a fast response, instant messaging is what you would normally use since emails are slow and sending an SMS uses up your monthly quota and can cost you money. Not all instant messaging apps are created the same though. Some instant messaging apps give you added security with encryption, letting you enjoy secure messaging that can even be used for business communications.
