Comcast has in fact blocked Square Enix emails. (please see threads under General discussions). I called them myself and said they would temporarily lift any block from Square, but I do not have any new emails.

Square Enix needs to handle this issue and unblock their IP address so Comcast email users can receive their key/invites. There is a form they would need to fill out to remove the block. Comcast told me that the reason SE is blocked is due to the amount of email they have sent and the volume of comcast users that have flagged their own personal email as spam. Some may have gotten through, however, after thousands of attempts and now Comcast emails are blocked.

Can a community rep or someone that can resolve this please fix it?! You offer NO support via phone or live chat.

Also, Comcast says that once the email is flagged as spam in their system, the email is deleted and cannot be recovered. So, us Legacy with Comcast will not get the invite.

Any way you can update the key/invite on the actual Square Enix account system? Seems that would resolve it 100%. Either that or we call have to use an alternate email or wait for weeks for you to resolve the spam issue and be put on a "white list" which means no matter how many emails you send they will not be flagged as spam.
