Blog Summary Page

Hi, We have a blog summary page at our website - onnalomd.com/blog On this page each post can be seen. However, this isn't the same as the individual post's urls - website.com/blog/post-1 We are using email newsletters and social media to link to individual posts as they are published. We'd like our blog summary page to be a more summarized version of posts aggregated on this page. That way readers who land on website.com/blog will have to click through for the individual post content. How is this done? Thank you, Onna
