I know others have had success with it… eZines have become very popular and if it's a decent size list, niched, relevant to your product, why wouldn't you be successful at it? You have more control. You know what your audience will be.
Ezines are especially a good thing if you can write an article for an eZine. You establish your expertise and create interest within the article and have a link to your site or product… I like the sites that send out their eZines and post your article on their site (with a link back to your website)… best of both worlds.
Like anything there is going to be a lot of factors involved… Volume, Quality of the content, how qualified the list is (hopefully an opt in crowd)… not everyone will produce. It's text, it's relevant and targeting a group of people who have interest in what you're doing.
The folks at Pure Leverage have put together a list of various solo ad sellers who consistently provides the best optin rates for your dollar. They can be found in your Pure Leverage back office where you will be able to see reviews which shows how their service converted, how much they cost and how much they ended up costing per lead.
You know you can certainly pay to advertise in eZines, but I personally love FREE advertising. And doing a Joint Venture with someone that has something like an eZine is a perfect way to do it.
You can create an eBook or Report targeted to an eZines readers. To give away! There are a lot of eZine publishers that would love to do that. Why wouldn't they want to give their subscribers something free. It's a great reflection on themselves.
That's how a lot of people build their e-mail lists. They swap advertising or put together mutually beneficial deals.
There's very little investment… just a little effort.
Here's a good article I found about Joint Ventures that sums it up nicely…
I just know from my research it's a great method used by many. I wish I had more time to pursue it… I can't do everything.
It's not necessarily limited to any particular product. If there is an eZine related to your product or website, there should be no reason you couldn't get traffic.
