It's just an email address for your Facebook communications. Facebook has long aimed to make its Facebook Messages hub a competitor to Hotmail or Gmail. Your email address has been assigned to you and is simply *email@example.com, where your username is whatever appears after "facebook.com/" on your personal profile page.
In other words, it's not really its own product; instead, it's part of the overall Facebook experience. If you want to send an email message from Facebook, then your email address will be used as specified above.
@facebook.com The email address displayed on a person's Facebook profile is the "@facebook.com" email address by default. This address is different from the actual email address used by Facebook to send messages and updates to the person.
A person can edit their Facebook email address at any time. When they do this, a new email address is generated for them. You can see your own Facebook email address by going to your Facebook settings page. Under "Email", click on the "View my email addresses". A screen will appear with all your email addresses; include your @facebook.com address in this list.
People can use any email address they want as their Facebook account address. However, if you need to contact them using other methods (such as through a phone number or physical address) then they must provide you with an email address that matches one of their Facebook accounts.
Facebook users can set up custom email addresses for themselves. For example, if someone wants to create a Gmail account but still have access to some of their regular email boxes, they can do this by setting up a custom email address using @gmail.com or @googlemail.com. When they do this, any message sent to their custom email address will be delivered to the corresponding Google account.
You must give an email address when you join up for Facebook. On Facebook, this becomes your primary email address. All messages, such as notices that someone messaged you or that a user signed in with your account from another computer, are sent to your primary email address. Your primary email address can be different from your real name on Facebook.
Your primary email address can be updated in your Account Settings page. If you don't do this, then even if you log in from other computers, Facebook will use the first email address it finds in your Facebook data it has on file.
As well as using your email address to send you notifications about things like friends' updates and comments on your posts, it's also used by Facebook to respond to support requests and remove blocked users from your account.
It's important to remember that this is only one method through which Facebook may contact you. For example, they may send you emails at your primary email address if you have not adjusted your email settings recently. They may also send you notifications (including text messages) on your phone number. Finally, they may send you letters via postal mail.
In addition, just because you delete something from your Facebook history does not mean that it has been deleted from Facebook. It may still be available to others who have access to your personal information, such as your friend or employee.
This is because Facebook is transitioning all of its workers to @fb.com email addresses in order for them to utilize @facebook.com for its new messaging service. This is the auto-response email we received previously. Dear Friend: Facebook has changed the domain of its corporate email address from @facebook.com to @fb.com. Your email address on file with Facebook is still valid, but as soon as you send an email to that address, you will receive a message explaining the change. We recommend that you update your emails to reflect this change.
You must enter an email address when creating a Facebook profile, whether it is a third-party account or a Facebook account. This protects your account from being hacked and allows Facebook to send you email notifications.
You have the option of adding numerous email addresses to your Facebook account. When you signed up for Facebook, you provided an email address, which became the primary email address on your account. Once you've linked numerous email addresses to your Facebook page, you'll be able to check in with any of them. You can also send messages to all of these contacts at once.
To add an email address, follow these steps:
Fill in the vanity username of the Facebook user you want to email, followed by @facebook.com. To send your message, click the "Send" button. Your email will appear as a new message in the recipient's Facebook messaging area, and a little envelope symbol will indicate that the message was sent from an email address.
