I visit Gamedev on almost a daily basis, but sometimes I'll miss a few days and that's why I'd like a short recap of the important things I've missed. The daily newsletter clutters my inbox.
I don't think the people who visit this website regularly are waiting for daily newsletters, because there's not much added value. For non-regular visitors, I think it's best if you get their attention by hitting them with your good stuff, not the day to day things(no offence to anyone).
I know from first hand experience that increasing the newsletter rate can really hurt your open and click-through rate, so keep an eye on that.
