This tutorial describes and explains what the “WPeMatico Publish 2 Email” addon is for., available here.

WPeMatico Publish 2 Email makes it possible to automatically and remotely publish via email from the feeds of your choice, using any of those clients on your autohosted WordPress site!

This addon allows to use WPeMatico from a WordPress website and send the posts obtained from each campaign to an email account. Each campaign allows you to send content to a different email account. Therefore, you can publish from a single website with the WPeMatico plugin to many different websites.

By not posting locally, it improves performance and reduces server load on both websites.
