I also prefer to receive as many newsletters as the programs can send out, that makes my job much easier. Some programs I promote don’t even send one in a month, it’s a bit frustrating, as they are always in the end of the updating queue. 
I have found to subscribe players’ newsletters more effective, it seems that these newsletters are updated more frequently. Though I would like to be ahead of player newsletters and get the news out to my players before they get the player newsletter.
