Little question about e-mail

Yes you can activate the game in any account given that you press the link on the email when logged in with that account.

So I can get the game in any email, I just have to be logged in my Steam account then ?

You can get the game in any email you have no matter what. There will be a link in the email that you can click, and then you will have to log into steam.

Thank you very much for the answer.
Seriously, thank you very much ! (^_^)v

And, well, about your mail, contact with the Steam Support. If your steam account is linked to a disabled mail, that can't be good.

I did it. I recovered my E-mail today (Finally !) and already linked it
Thank you very much ^^

yeah, i had a disabled email linked to my steam account once. then i deleted my cookies and passwords. Didn't even think about it. Took a week for steam support to give me access to my account. Doesn't matter if you remember your user name and password. that email is the most important thing linked to your steam account. Because of that I suggest using a separate email account actually. That way no one knows the email address that is linked to steam and your steam account stays safe.
