Gigi, you're certainly okay if you didn't open the email. More often than not, and especially if your a/v software scanned the email, it would be safe to open. But I would definitely
not click on any links that are inside the email itself. If you've already deleted the likely bogus email, that's a Good Thing. But don't ban or blacklist the domain.
After asking Nytefall and Roeksha about the address you provided, it doesn't seem to actually exist. But it's insanely easy to fake up or spoof a sender address.
Just a bit of background info: I've received literally dozens of phishing emails that were
supposedly from Blizzard. Opening them isn't an issue--you can do that pretty safely. If you do, and your mail reader allows it, take a look at the full message header, which should show the actual sender. Chances are excellent that it came from a Gmail or Hotmail account. The majority of the "Blizzard" phishes I've received came from various Hotmail accounts, but were spoofed (faked) to show they came from Blizzard, or from Battle.net. I've also received phishing emails for RuneQuest (several) and Rift (one).
I've never had a WoW or Battle.net account, nor a RuneQuest account. I have had a Rift account, but it's inactive.
One last thing. If you receive either the US or EU newsletters, the sender will always be
noreply@news.runesofmagic.com. If, and heaven forfend, that your game account has been suspended, you
may receive an email from
support@frogster-online.com to inform you of this and that you should contact Support. Obviously, if you have contacted Support, for any reason, you'll receive an autoreply from that email address.
