Custom Post Type newsletter option

I have a Book Review section on my blog using custom post type. It has all these options:

'supports' => array( 'title', 'editor', 'excerpt', 'author', 'thumbnail', 'comments', 'revisions', 'publicize'),

But when I want to post a book review I don’t have an option to also send it as newsletter to my subscribers like I do with my regular blog posts. I do have the social media share options, but not the newsletter.

Is it possible, am I missing something?
