You need to navigate to subscriptions and uncheck a couple boxes there. Whenever you claim a free game, they automatically subscribe you to their newsletter and marketing email list, and you have to unsubscribe again.
when you accept a free game on GoG you agree to join their newsletter. What I did after resubscribing every time I got a free game is just make a rule in my email client to delete them before I see them
Oh, I got the Alone in the Dark trilogy the other day yeah and I don't think I ever got a free game on GOG before. But I'm pretty sure I unsubscribed from their newsletter when they sent the email this Thursday. I did it again, I hope it works this time, else gonna have to contact support.
