Hi Ramon, thanks for contacting me. I will see why you get the same articles and I will let you know.
The issue has been fixed now. You should no longer be redirected to the articles list but the article itself. Thanks again for reporting the issue and let me know if you have any other issues.
Hey Jakub, yes I see now. Thanks for letting me know, I will fix it right away.
Hi Jakub, I just tried it and if you are not logged in and it will open the popup and after you login it redirects to the source page. 
Do you have an example where I could see it because I can't seem to reproduce it?
Ok, I see the issue. I am not sure why you got that email but I will check it out. Thanks for letting me know.
Do you have issues with unsubscribing? If yes than there is "Unsubscribe" link at the bottom of the newsletter email.

Did I understand you correctly?
Hey Alvin, yes, I will make that functionality but it will have to wait for a couple of weeks because I am in a middle of creating My page section and that will be the next task.

Good idea, thanks!
