Email not working on Twitch?

I wanted to register for Twitch again, but somehow it doesn't work…

I've entered all the data and then this window pops up.

I tried another email address and it didn't work again.

Do any of you know what I can do?

The easiest way to do this is to log in with the email address to which your Amazon account is linked (if available).

In this case the "blocking" can have different reasons. For the sake of simplicity, I would create a different e-mail address for you and set up forwarding of all Twitch e-mails to your normal address.

Otherwise, please contact Twitch support.

Unfortunately, it didn't work with this email address…

I have now created a new one and linked it.
