User blog comment:BertH/Introducing Announcements, a new way to notify your community/@comment-26084508-20180718073322/@comment-5275700-20180718173456

We don't have any plans for a tool to message to logged-in readers who have not contributed.

As a reader, if you want to receive announcement notifications, it's very easy to participate casually in Discussions (even upvoting makes you eligible) or to edit your user page on the community.

As an admin, you can leverage Discussions as a way to engage the readers with conversations, polls, and drive them toward actions that will make them eligible. Ultimately this will help build real engagement on your community and keep people coming back, more than the "shout in the dark" method.
