what is "certified mail"?

Question

I want to mail something, but it says not to use certified mail. What is that? and what isn't certified mail? Thanks!

Answer 1

With certified mail someone signs for it and then you receive a receipt that proves that it was mailed and received. I would be suspicious when they say no certified mail since it costs them nothing.

There is an extra charge to the sender for the service.

Answer 2

Certified mail requires some one to sign for it. regular post is just dropped in the box.

Answer 3

it is an anachronism, a dated form of communication, which is still required by certain processes. It serves to prove that something was delivered, as the addressee must sign for such a piece... but what it doesn't do is prove what was sent.
