That would be great, if they did not just direct me to my desktops mail, and have there email hidden behind multiple walls. I have not emailed them nor should i have to, they offer a service there for they should be sticking to there protocol's.
...The itch.io support page lists the official e-mail very visibly right there. It's an ordinary e-mail address that you can use with any client and provider. Check your browser and/or system settings. This is the correct way to contact support, because itch.io staff needs to check who you are, and that's not possible just from a forum post.
