Combining Newsletters and Blogs
Before syndication of content (feeds, that is) was an alternative, I had very positive experiences from publishing newsletters. A great way to remind the audience of your existence. It is also a more powerful tool if you want a designed environment for your message, or if you have several messages that reinforce eachother.
So what about newsletters and blogs working together? Nick Usborne points to a couple of relevant articles, and I think that AdRants is a good example of how it can be done.
