OK .... bare with me here...I'm not quite sure how to explain this. This is a pet project of the CEO of one of the companies I work for, and I have to come up with some marketing ideas for it. In a nutshell here's how it works - 1) You (a buisiness/website owner) sign up with them. 2) They provide you with signup banners etc for you to place on your site. 3) Vistors to your website signup to thier newsletter but under your account. 4) They send out daily and weekly newsletters (very high quality and useful stuff) and the only adverts in the newsletter are yours. You have full control and can switch ads in real time. Make sense? They supply all the content and take care of delivery etc. and you just supply the ads that will be displayed. The content is agregated and reworked from patent offices around the world and so it is purely informational and interesting. The stats are phenomonal! 97% retention, opening rate 35% on a daily newsletter that has been going for a few years! They don't mention any offers or products at all - any offers will be yours. It's been very much a labour of love up to now, but he's looking at trying to monetise it soon, and we're looking for ideas/feedback... There's currently a 60 day free trial, but this is changing to a new model where it will remain free as long as you have under a certain number of subscribers (50 I think) and after that it there is a small fee. Give it a whirl (signup at http://patentdata.com/register.php) and throw me any ideas or sensible feeback. There are also a couple of examples of the latest newsletters on the signup page.
