According to Techcrunch's sources, a full webmail client integrated with The One and Only Social Network will debut next Monday. This is why it may become your favorite webmail service.
If I were Google, Yahoo or Hotmail, I'd be very nervous. Facebook Mail could be a killer not only because of its potential instant size, but because of its natural advantage at making mail more useful.
That's the important thing for Facebook users and everyone else. This may become the only 100% useful mail service out there, only showing you the emails you are actually interested in. To me, if they have the right user interface, that's enough reason to switch from Gmail.
Facebook has 500 million active users. Gmail is estimated at 170 million registered users, while Yahoo has 303 million and Hotmail is still king of the hill at 364 million. Of course, not every Facebook boy and girl will jump on its mail bandwagon, but chances are that a huge percentage of you will. In fact, it's not a crazy assumption that almost everyone will, even if that means having yet another mail account added to your computer, phone or tablet.
The fact is that it may be just too convenient to ignore. Facebook users are already used to its internal messaging system. For many, this will be a nice upgrade that will let them add these messages to their mail boxes. Remember that Facebook's mail is rumored to have external mail client access as well as its dedicated webmail interface. It will be easy to have it in every single gadget you own.
But, most importantly, Facebook's users would probably jump in because the social nature of Facebook fits perfectly with the social nature of mail. The irony here is that their mail system could be a raging success because of what many people criticize: Facebook tracks all your moves.
Since Facebook knows how you interact with all your contacts, they would be able to perfectly separate what is important from what is not. Having used Gmail's Priority Inbox for a while, I have the feeling that Facebook could do much better at given all their data and some clever, but not overly complicated logic.
Moreover, it's not only about separating what is important and what is not. Their data tracking and analysis could allow them to do many other things. For example, they just have to analyze who is tagging you in photos, who is with you in those photos, to know who are your real friends, and categorize mail accordingly. They can automatically classify mail from the person who just became your fiance or lower the priority of that ex who keeps mailing you. The possibilities of using your social interactions to enhance the mail experience are endless. I have no doubt that Facebook will exploit this information to your advantage—and theirs, I'm afraid.
Ultimately, that's what people—especially younger generations—like about Facebook. It's always prioritized communication, a closed playground where only your friends and contacts get to interact with you. If they can provide a mail system that will allow the controlled entry of external people while keeping the playground fun, clean, and safe, they'll have a winner. [TechCrunch]
