Here’s what it said:

I do not wish to receive your newsletter. You send info far too frequently.

This person feels my twice-monthly newsletter is too frequent.

And yet you signed up for a “near daily blog.” (Are you insane?)

There’s no perfect frequency of communication, since different people want different things.

I have found, however, that in general, and in terms of building an audience and from that, a base of clients, more frequent publishing is better.
