Don't be fooled by Gmail's promise for confidential emails.
Gmail's new confidential mode for emails is neither secure nor private. At its best, it is a fun feature to help your
recipient achieve inbox zero. At its worst, it is a privacy-intrusive feature that does not achieve true
confidentiality. In fact, for sending a confidential and secure email, end-to-end encryption is a minimum requirement,
and Gmail has long abandoned this approach.
