Having others edit blog posts

I'm a newbie, I'm curious if there is a way to submit your blog page to someone to look over/ edit first without publishing. I want others to see how it would look live without being published.

Thanks and regards

Assign someone editor permissions. They can do anything to a blog post that you can do.
