I received an email that I created a new Facebook account, but I didn’t create a new account.

Most likely, someone tried to create a Facebook account using your email by mistake. If this email isn’t confirmed, it won’t be added as confirmed to their Facebook account.
The easiest thing to do is ignore the email. You can also:
  • Click the link at the bottom of the email to let us know this wasn't you.
  • Add this email to your account, if you have a Facebook account.
  • File a report.
