Sending a message is quite simple these days. This is good thanks in part to the advancement of the technology. Instead of picking up the phone and calling someone’s home or even writing a letter earlier than that, you can today type a message and email to your friend or family member. You can also chat with your friends and family. These are two different types of communication.
Emailing is done when you want to send a lengthier message or one that is private. If you have an attachment, you can email. If you use chat, it is because you want to send a quick message to a friend. Usually, people do not send attachments when they chat compared to when they email.
