Fortunately, Hop has found a way to make this easier. Essentially, Hop morphs your inbox into a messenger tool. You'll quickly be alerted to when you have a new message in your inbox and can even see someone responding to a new email, similar to iMessage.
Push notifications can be customized for different types of messages and contacts, so your phone doesn't alert you to every message that comes in.
Today, Hop launched for the iPad and gained a bunch of new features for the iPhone. You can download it here.
