I just received an email from Blizzard with the title "Welcome to the Hearthstone: Heroes of Warcraft Beta Test". However, when I opened it, there was no key, just a button that linked me to page I'm supposed to enter the key on. After a quick google search, it became apparent that I wasn't the only one with this issue, so I was wondering if anyone here knows the deal.
I sort of doubt that it's phishing, the email seems to be from Blizzard and the link takes me to battle net, where it prompted me to log in and then enter a nonexistent beta key.
That sounds exactly like phishing on every front. :/
Hopefully you double checked the url.
