Gmail introduced a confidential mode in 2018. The ability allows users to send messages that expire and prohibits recipients from copying the content, forwarding or downloading them. The Verge reported that Google uses standard encryption called TLS that keeps the emails secure in transit. For businesses and institutions, Google has S/MIME (Secure/Multipurpose Internet Mail Extensions) encryption offering more security.
