In case you do not use the Jetpack plugin for your WordPress site you might want to consider it. The plugin is packed with some professional features. One of those really cool features is the Subscriptions feature. Not only is it easy to subscribe on a WordPress site – see my home page on the upper right for an example, the administration of the subscriptions is basically seamless.
Many visitors land on your site once, never to return. Convert more visitors into regular readers by making it easy to subscribe to your site so new content is pushed directly to them. Jetpack takes care of letting them know whenever you publish a new post. – link
Once your readers are subscribed, you no longer have to worry if they will see your post because they will get a nicely formatted email with your post and content. Check out a screen shot of my last post in my GMail account:
