Are there ad networks for newsletters? Or is it better to just go the HARO route and sell your own ads? Just curious on what people's experience has been.
To my knowledge there are no ad networks that exist for email newsletters. This in part because the inventory is difficult to standardize. You essentially have to hardcode images into the newsletter - you can't just "drop a line of code" like you can with a website.
This makes me wonder if there is a market for that. Idea: a newsletter / email marketing solution complete with an ad network. The content of the newsletter could be used for targeting ads. Some kind of mail chimp + adsense looking product. Thoughts?
I had (varying) success mostly by selling sponsor spots. It let me (crudely) target the ads depending what that issue of the newsletter was discussing.
