If you have an account with fanatical.com, you “might” get an email titled “Your Secret Santa gift is inside! Claim yours now”. Check to see if you got that offer. I did, and got a nice game for free (the link in my email was usable only by me, so I can’t share it). 
I got this game (yours may be different):
They are different. I already had it so I gave the key to another. 
I didn’t know what game they tried to send me until I registered the key at Steam. I assume you did the same, and then saw you already owned whatever they sent you?
Thanks for giving that key to someone that wanted it, so nice of you (as usual). 
Once you click to reveal the key, the name of the game shows up on the left side on the Fanatical page, you don’t need to try to activate it on Steam to find out if you already have it.
Oh no. I remember Mystery Keys being anonymous before, so I just redeemed. It was This War of Mine, which I think I own on Epic already. Myrr.
aww, i didn’t get that email 
now i feel so left out, and i even visited them dec 1, and they already forgot about me
Maybe they’re rolling out slowly? One guy told me he got an email on his 2nd Fanatical account. No idea why he has two, heh.
Do you have an account (userid/password/login)? Have you ever bought anything from them? Yes @Danacscott also points out they may take time to get to everyone. Also, it might be a random/luck group of emails based on giveaway stock? I wish you luck getting an email. 
it says it’s for those who are subscribed to their promotional emails only afaik
oh yea that would totally rule me out 
Yeah I get emails from them but only the wishlist ones lol if I had known I would have haha
I’m assuming anyway mostly weird games
Walking Dead Season 2 this time for me. Likely to go into a parcel in the new year. 
yeah, i subbed to their emails so i wouldn’t miss some of the insane daily deals they sometimes have, or like rly great games for $1 now and then
For those not subscribed, I suggest you go to your account and subscribe. You might still get the email.
meh, some rando game isn’t really worth the 3x daily fanatical spam email for me, i got Itad notifications for when they got good deals pertaining to me
My. Grumpy, we are.
I also don’t think a random game is worth all of the spam from Fanatical. lol I was getting 5 emails a day if it were a slow day. I had to remove it.
