Your newsletter is all yours. Unlike with social media websites like Pinterest and Facebook, your newsletter and email subscribers are all yours, and you have their undivided attention. You don't have to worry about some social media algorithm not showing your content to your readers, as they are your email subscribers so you aren't fighting with anyone else to have them see your content.
Make it easy for readers to browse – If you want more pageviews, you should make it as easy as possible for readers to read your other blog posts. You will want to make it easy for readers to find your blog homepage, categories, tags, search bar, and so on. Also, I recommend including links in every single one of your blog posts, so readers can easily find related topics.
