Nowdays, using email is very popular all over the world. But many people think it is disadvantages. In my opinion, email brings us some benefits because of some reasons. Firstly, email helps us exchange information faster. Instead of using snail mail, you can receive email which you will save time to do anything more. With email, the recipient whether you are halfway around the world or at the same room working with you, sending and receiving mail is done almost immediately. And the cost of those letters is equally cheap.Secondly, thank to email, you can make many friends even foreign ones. If you are lucky enough, you can find a real friend. Lastly, With normal correspondence, you have to spend a considerable amount of money when sending your letters. As for email, you only have a very small fee to connect to the internet with the cost of your email service.You can also use the free email service. At that time your costs for the letter are almost negligible. In short, using email is very good for us so I think using email will be more popular in the future.
