Letters from machine

Haven't received any email from 'human beings' for a long time, although I have some 10 new emails every days. They are not junks, but some subscriptions from some websites such as news updates, A Word A Day, etc. Likewise, I receive letters two or three in a week, but none of them is written by human beings. I've got a lot of letters from machines. Bank statements, credit payments, promotional letters, etc. I started to doubt if technology improves relationship again.
