Regarding Furniture Design Contest Email Not Reciving My Entry

Hi. I am writing regrading the furniture design contest, concerning my entry. You see, I entered my entry before August 28, 7:59, using gmail to send to the company. Yet, a day later, I got an email saying this:

The response was:
The recipient server did not accept our requests to connect. Learn more at https://support.google.com/mail/answer/7720 [sqaure-enix.com 199.191.50.73: timed out]

I'm not sure what it is, other than that the email I send to ffxiv_contest@sqaure-enix.com did not receive it. Is it a glitch or something? Please respond.

It looks like you simply wrote the email address wrong. It's square-enix.com you put sqaure-enix.com

I feel embarrassed.
