All project mail or transmittals you send are visible to all recipients and everyone in your organization - this article shows how to hide them by making them confidential.
If you have potentially sensitive mail that only certain people should have access to, you can mark it as confidential before sending it. This means that only the recipients of your mail will be able to view it. Before sending a mail, make sure you check for any automatic recipients set for your project. You can do this by choosing to Preview your mail before sending.
Organization Administrators may choose to authorize some of their users to view all confidential mail received by their organization.
