I'm building an identity card for newsletters. What do you think?

I'm creating a "newsletter identity card" for each newsletter I interviewed about for my newsletter, Newsletter Circle.

This is the first step to building a directory of newsletters.
Additionally, knowing other newsletters' key info and metrics may help to shape ours.

What do you think about the below table? Which other key information should be added?
