12. Email Collaborators

When you initially share a Google Doc, collaborators will receive an email, in which you have the option to compose a note. Beyond that initial email, however, the only email they'll receive going forward is either a notification when a suggestion they've made is acted upon or when they're tagged in a comment. If you'd like to email all collaborators, maybe to tell them you're ready for their final review of the doc, Google gives you that option—"Email collaborators…"—under "File" in the menu bar.
