OneSignal push notifications

The OneSignal push notification service is free and provides all the necessary features to notify your users of various activities as well as contact them via their dashboard. To enable it, you must first create an account with them. Once created and logged in, create a new app that will be used by your website to manage subscribers and send push notifications. When asked for a "platform type", select "web push" and hit "next".

You will need to create a new prompt for your app. What this does is basically displays either a small "subscribe" icon in the corner of your site or a notification slider at the top when your users first visit. You may choose whichever one you prefer.
