Write about advantages of email ( from 150 words -> 170 words ) Please help me !!!

In the old days, they used to write letters by hand and post them at the post office. Now that information technology has evolved, they have created email, a tool to help write letters, receive mail, send pictures and other things to help with the work. Advantages of email help to shorten the time and distance between sending and receiving messages. There is no charge, the content is clean, easy to read, easy to communicate, but does not take much time to write a letter. Especially the security is very high, letting us know who is hacking the account to get information. That is why email is always received by many people around the world.
