Today, email messaging has become the primary means of exchanging information and documents. Corporate mail in a higher education institution means high work efficiency, security, the ability to use corporate standards and a common address book, uniform rules for sorting mail and settings, the ability to organize group alerts, meetings, etc., the ability to store mail on a server, rather than on local computers. The exchange of official information by e-mail between structural units, as well as between employees, is an official method of communication.
