This tutorial describes and explains how WPeMatico Publish 2 Email works, available here.

WPeMatico Publish 2 Email will use the campaign settings to get the content that will be published automatically, but now the posts will be sent to an email address, then on the destination website you can use some automatic service (WP via Email, Postie or Jetpack) that will take care of reading and publishing them on the blog.
