One of the coolest features of site builders like Squarespace is the ability to create a marketing email directly from your blog. This would be a great feature to make it a one step process. Once the blog is written, simply schedule an email blast to bring your audience to the site to read it. Right now it is a process of back and forth, copy, paste, remember the publish date, etc. This would make a seamless process out of something many of us do.
