Have fun analyzing :)
I don't think it's country based however. I think if at all it would make more sense to base it on previous orders.

I did buy some games recently (maybe a few weeks ago) with codes i got from the forum. I also thought about that when i first noticed not getting any codes anymore :-)
Thanks for the effort :D
I am wondering though why you didn't get the recent ones. I remember back in the days even getting codes for games i already owned.

I didn't notice that until this thread and I checked the thread
Maybe I'm being punished :D A couple of weeks ago I posted a code in the forum for someone else to use.
But honestly I don't think so.

For what it's worth:

-I use GMx too, and my GOG account is linked to my GMX mail account.
-The last exclusive discount I received is the one on Ubisoft games, on 13/04.

Update on this whole issue:

A few days up to a week after i contacted support, i had E-Mail contact with a staff member who did send me the newsletter discount codes manually in his replies while trying to solve the problem.

After about 6 weeks and several E-Mails later i finally got 2 Newsletter codes and informed the support that it finally worked.

Disappointingly enaugh that wasn't the case since i stopped receiving Newsletter discount codes again so i contacted support through the last E-Mail (reply) again. I also removed the Steam connection from GOG Galaxy.

After about 2 weeks i finally got an reply by another staff member. It told me that they might figured out what the problem was and that i should be patient a bit longer.

A few days later i got the last E-Mail which statet that the problem was solved and that it must have had to do that i flagged the newsletter as Spam (which i didn't - i checked everything before)...

I really don't know what they did in the end but after their last reply i am receiving newsletter discounts again. There was still one code that i didn't get (saw the code in the forum - ENCODYA) but the problem seems to have been fixed.

The whole journey took about 10 weeks and some E-Mails but in this case the end result counts and i am thanking the GOG staff for fixing the Problem and everyone who tried to help me in this post :-)

I also don't get all discount codes, but I get some.

It seems to be quite random.

They did mention that owning too many games which are affected with the code could disqualify one from getting the newsletter code.
Considering the codes i got lately, i can't confirm this theory.

I guess by "too many" they mean all, since I often get a code where I can only claim one of the games.
