How Do I Automatically Send An E-mail Campaign Every Time A Blog Post Goes Live?

I am desperate to get all of my e-mail marketing out of Mailchimp and into Squarespace but I cannot for the life of me figure out how to do an automated e-mail campaign where people receive an e-mail every time a new blog post is published. Is this possible? I basically want to create a template that is populated and triggered by an RSS feed. 

Like this: https://us11.campaign-archive.com/?e=95ace6cb16&u=40a022775bd326fb61d6fd9e4&id=e97973261b

I run a collaborative blog that publishes essays 3x a week. How can I sync our new content with an e-mail campaign? Some people prefer to read via e-mail ... 

There's not really an automation feature as such but you can turn a blog post into an email campaign but you have to send it yourself.
