I'm trying to contact itch.io support, but the e-mail they provide (support@itch.io) bounces back and says it's not a valid e-mail.  Am I spelling something wrong?  Is this maybe just a temporary issue?  I'm getting worried that there's no way to contact them, thanks!

Someone else just complained about it. Could be a temporary issue with the e-mail server. Just in case, try attaching another e-mail address in your account settings and use that one instead.

Edit: there are multiple reports of e-mails bouncing on the Discord server too.

My email to support also just bounced.
