Consider the 8 default post statuses that WordPress uses by default: 
* Publish: Viewable by everyone. (publish) 
* Future: Scheduled to be published in a future date. (future) 
* Draft: Incomplete post viewable by anyone with proper user role. (draft) 
* Pending: Awaiting a user with the publish_posts capability (typically a user assigned the Editor role) to publish. (pending) 
* Private: Viewable only to WordPress users at Administrator level. (private) 
* Trash: Posts in the Trash are assigned the trash status. (trash) 
* Auto-Draft: Revisions that WordPress saves automatically while you are editing. (auto-draft) 
* Inherit – Used with a child post (such as Attachments and Revisions) to determine the actual status from the parent post. (inherit)
A typical publishing workflow would be: 
 Auto-Draft > <code>Draft</code> > <code>Pending</code> > <code>Future</code> > <code>Publish</code> 
But what then? <code>Trash</code>? <code>Private</code>? These seem inadapted.
This is where the Unpublished (unpublish) post status provided by this plugin comes into play. 
It allows content publishers to assign a dedicated status to content they desire not to be published, and avoid assigning a semantically inaccurate status.

WP Unpublish

WP Unpublish adds a post status "Unpublished" to your WordPress Posts (Classic Editor).

WordPress lacks the ability to schedule content updates. Keeping your posts and pages up to date manually can often be a waste of valuable time, especially when you know you’ll need to update the same page again soon.
<h3>Use Cases</h3>
<ul>
<li>Promotions: Automatically publish versions of your pages that contain temporary promotions and schedule content updates that remove these promotions once they expire.</li>
<li>Events: Schedule content updates for pages that list events. Automatically publish an updated version of the page after an event ends.</li>
<li>SEO: Schedule series of content updates to keep your pages and publishing dates current and satisfy the freshness algorithm.</li>
</ul>
<h3>Key Features</h3>
<ul>
<li>Updates page content and publishing date</li>
<li>Compatible with any post type</li>
<li>Compatible with Elementor and Oxygen Builder</li>
<li>Nested content updates (multiple updates of the same page scheduled in a row)</li>
<li>Lightweight code</li>
</ul>
