If you have comcast, call them immediately to remove the block

I just got off the phone with Comcast. Square Enix emails have all been blocked because of the number of people that have flagged their emails as spam. Because so many of them went out today, they are all blocked.

Even if you do not have it flagged as spam, too many people do and you will not get your email. Call them now and have them temporarily remove your email from their block list.

Hope that helps you all-

I take it that solved your problem?
