Nelio Content can automatically share the social messages you have created. You can write this messages manually or you can click on a button in the Editor and let Nelio Content automatically generate them based on your post’s content.
If you have an active subscription, there’s no need to explicitly create these messages: when a post is published, Nelio Content will automatically create and share one social message per network to promote it. But, again, this only works for subscribers.
