Facebook is completely rewriting their messaging product and is preparing to launch a fully featured webmail product in its place, according to a source with knowledge of the product. Internally it's known as Project Titan. Or, unofficially and perhaps over-enthusiastically, the Gmail killer. There will be full POP/IMAP support, meaning users can access the account other than through Facebook itself. Your email account name will be your vanity url – vanityurl@facebook.com.

Project Titan is said to be not only a webmail service, but also a complete rewrite of the current messaging service which the company uses. A few people have expressed complaints about their current messaging service, believing that it is too slow and frustrating to access when almost everybody uses email nowadays (you can receive emails when you get Facebook messages, but you still have to go through the site to interact with people). The company aims to make their social network the best possible experience it can be, for various obvious reasons, and this improvement will be extremely welcome.

Project Titan, while being a webmail service featured on Facebook, will have a few additions to make it much more accessible to those who use messaging regularly. First of all, you'll get your own email address; it'll be your vanity name (the one you chose for your Facebook.com/username address) at Facebook.com. Project Titan will also provide POP and IMAP support for the addresses, meaning that you'll be able to add the account to various third party services, and even mobile devices, should you desire to. In short, it'll be exactly like a regular email address, except it'll go through Facebook.
