Why am I getting a Facebook invitation email from a friend?

You received this email because a Facebook member is inviting you to join Facebook. Facebook allows members to send invites to their contacts by entering an email address or by uploading their contacts.

If you're already registered for Facebook, your friend may have submitted an email address of yours that is not currently linked to your Facebook account. If you'd like to, you can add this email address to your existing Facebook account to ensure that you won't get Facebook invites sent to you in the future.

If you are not already a Facebook member and would like to join, you can use this email to start the registration process.

If you wish to no longer receive invites from your friends, you can use the unsubscribe link in the footer of the email.
