Email scam or real?

Hi im just wondering if this is a real auto message from blizzard or not, it regards email change notification. which scared me a bit as u have to be in the account to change the email.

Hello,

Blizzard Entertainment recently received a request to change the e-mail address used to log in to the Battle.net account with the username (edited out). The e-mail address (edited out) has been specified as the new username for this Battle.net account. An email has been sent to this new address containing a verification link to complete the change.

Once the new address has been verified, the e-mail address (EDITED OUT) can no longer be used to log in to this Battle.net account or any World of Warcraft accounts merged with this Battle.net account.

If you did not initiate this request, pleaseto contact the Blizzard Billing & Account Services team immediately.
