brainCloud messaging is a one-to-one conversation in general. That means the profile Id of receivers must be explicitly designated when sending messages out. That is different from chat which messages are accessible to everyone who connects to a chat channel.
Messages persist over time. They can be retrieved later if the receiver may not be online at the time they are sending. The paradigm is similar to email, but messages stay within your app.
