maybe you should include what info your email newsletter consists of on site
I do not want to buy a cat in a bag
as for the newsletter itself,simple info like: price movement,node count,Segwit vs BU percentage,average median tx fee
breaking news(only a few,maybe 2-3 most important),pool hashrate distribution,total hashrate,difficulty etc.- pick and choose any
if you could assemble all of the info in one short newsletter-count me in
