That used to happen to me at the old site- newsletters, sale notifications used to go to the address I first signed up with even though I changed it not too long after to my current address… all other DAZ notifications I got correctly…. I tried several times over the course of a year or two and it never took… One day I mentioned it in a thread and RH took notice and fixed it for me.
