I have received a couple targeted (?) offers in the mail the past week for my Radisson card. One was add an authorized user and get 2000 points. I passed on that.
The other was a spend/statement credit offer that is not great and somewhat complicated. It was for a 1% statement credit per dollar spent (up to $10) after spending at least $250 in specific categories (gas, (groceries, and home improvement stores). It sounds like you have to spend $250 in a specific category to start earning the cash back, and you can earn up to $30 if you spend $1000 in each category (but you cannot spend $3000 in one category--it is like 3 separate bonuses). I am not going to complain that they sent out a promo, but I do not think I will bother registering for it.
