I was not subscribed (just did), but then again I just joined this community just recently and as such I cannot critique the current newsletter that you are providing. However, I can share my input on newsletter in general. Most often I sign up for newsletters, but after the first few I regretfully unsubscribe, because they are nothing more of cheap content such as links to hot posts on the forums and most often something like "Screenshot of the Month" depending on the kind of site your are... there is/was no added value to be subscribed to those newsletters.
While it is always fun and nice to have those allerts telling you: "Hey, some cool discussion is/was going on here. Check it out." I want something extra in my newsletter. Unique content that is unique to the newsletter, a unique selling point. Thus that is what I hope to find in a newsletter that little bit extra unique to a newsletter, though I cannot say what that would/should be.
I hope this was helpful in anyway whatsoever.
PS: If I remember, I shall share my opinion on the newsletter once I have received and read one.
