Certified email

Certified email (known as Posta elettronica certificata in Italy, or PEC in short) is a special type of email in use in Italy, Switzerland, Hong Kong and Germany. Certified email is meant to provide a legal equivalent of the traditional registered mail, where users are able to legally prove that a given email has been sent and received by paying a small fee.

Registered mail is mainly used in Italy, but there are present efforts to extend its legal validity according to the framework of the European Union.
