I think an email with a short summary of the most recent blog post and a link to the full article. Just something simple. Then, a way for me to know who has subscribed and receiving emails. Another nice feature would be to have a way to see on the backend, the number of people who have read a given post. Its available on the front end and users can see how many times its been read, but there is no way on the backend to track that info that I am aware of.
