Besides not being a subject matter expert, I don't have any evidence to support this assertion:

It feels like you're looking to get involved in an industry that's being disrupted (unless e-mail newsletters are going to continue in their current form, which I don't believe), but that your idea isn't causing this disruption. I feel like there's a pivot somewhere here, after some more time on it.

So in essence, I'm giving you the opposite of what you want; I think if you start looking into this further, you may hit upon the true solution. At least it sounded to me like you had the knowledge and interest to make it happen.
