Email vs Postal Service

I believe that email plays a major role in today's society. Email is faster than the postal service. We do not have to use stamps in order to send our messages. Thus saving money and time. How long does it take to send a letter through the United States postal service? Maybe 3-5 days depending on the location. How long does it take to send an email?? Wow!!! instantly basically...well close :) Which one would I prefer? That is a hard question to answer because both email and the postal service have their pros and cons. I believe that as humans we need both email and the postal service. Email can send messages through text quickly, but the postal service can send an actual item that we can touch and feel.
