A Proposed post will be sent to your company's admin(s) and Channel Managers for approval. Once the post has been approved it becomes available on Smarp's post feed. If the post does not show up on the post feed, it most likely has not been approved and is still pending.
You can always check your own 'My Posts' feed to see the status of your posts.
Tip: You can get notified in Smarp when one of your proposed posts has been approved by ticking the "Approved posts"-box in your notification settings.
