Settings: Writing -Publishing tools options managed differently between atomic + simple

[azollafox]

Steps to reproduce

1. Starting at URL: https://wordpress.com/settings/writing/DOMAIN
2. Go to "Publishing Tools" section

What I expected

I expected both simple and atomic sites to show the same Publishing tools options in Calypso.

What happened instead

Publishing Tools on atomic enables you to post by email. On simple site, you have to manage it from wpadmin > My Blogs
