- It combines SMS, IM and e-Mail together.
- Once you have @Facebook id, anyone can mail you using traditional mailing system.
- All the messages from someone who you really cares(There seems to be a privacy setting to control this) will reside in "Social Inbox".
- Rest of the messages like bank statement, credit card bills etc will reside in "Others" folder. It works pretty much like "Priority inbox" of gmail.
- You need not worry how the messages are delivered, If you are online the messages will be delivered to you as IM.
- There is no Subject,CC or BCC fields. The focus is purely on the message. Choose to whom you want to send the message, type the message and enter it.
- Entire conversation history is stored in your inbox.
- It now works on Invite only.
You can request your invite here. Go grab yours!!!
Note: Gmail was down shortly after Facebook unveiled its new messaging system.
