Control Who Can Deliver Content (or Links to Content) by Email
By default, everyone can deliver and receive content by email after you set up the email server. If you want to restrict email delivery, you can grant the Deliver Content in Email privilege only to specific users and application roles or you can disable the feature for everyone.
The option to deliver links to content in email isn't enabled by default. So if you want to allow users to email content links, you must specifically grant the Deliver Content Link in Email privilege to one or more users or application roles.
Note:
The Deliver Content in Email and Deliver Content Link in Email privileges apply only to content you create from the Classic home page, that is, analyses, dashboards, pixel-perfect reports, briefing books, and so on.
