Facebook email - what's the impact for education marketing?

The biggest digital  announcement last week was around Facebook's move into the world of email. The system is actually only in beta at the moment, so it's unclear what the full product offering will be, however Facebook has stated the following features will be included:

• Facebook users will be able to access a range of messaging formats in one place. The vision is that SMS and instant messages and email will all be accessible
• Facebook Messages will have a very high spam filter, creating what Facebook calls a "social inbox". You can set your privacy settings so your inbox treats messages from people who aren't your friends on Facebook as spam. Alternatively, all your non facebook friend emails will go into a folder called "Other".
• Messages will be more concise. Subject lines and CC and BC features will be stripped out in the new system.
