Send all your blog posts as email campaigns to your subscribers - as and when you write and publish them. RSS Campaigns let you schedule and set up campaigns for each of your posts. The emails go out automatically from then. You can focus more on writing your blog posts.
Once a month or one every week? You can decide how often you want to send out your blog updates to your subscribers. You are in constant touch with your subscribers.
You do not have to worry about creating separate content for your emails. Feed Campaigns automatically take the content from the blog posts that you have published.
There's a report for every RSS campaign that goes out. As a blogger, you can improve your content based on the results of your campaign.
