How valuable are Ezines for driving Internet leads and revenue?

I prefer specific email ecourses based around specific problems a particular audience is experiencing.

Ezine is spam. Google even once shut them down because the spam was that bad.

High quality Internet marketer?

...more like clueless marketer.

Seen their better days 7 years ago, imo

I think a lot of you are confusing Directory of Ezines with EzineArticles.com.

The DOE is a paid, curated directory of niche ezines run by Charlie Page. I've been a lifetime member since my MLM days.

DOE can be helpful in two ways, as I see it.

1. It can be used to source solo ads or in-issue ads to the ezine's subscribers. You have a good chance of reaching people not on the typical solo seller's list. And some of those ezines have six-figure subscriber bases.

2. Some of these ezines accept outside submissions, so you may be able to place relevant article with your author bio linking back to your site. The big thing to notice is that, since this is email, many publishers don't worry about the so-called duplicate content penalty. They just want content that makes them look good to their subscribers.

EzineArticles.com is a collection of articles available for you to re-publish on your site or in your newsletter. It's run by Chris Knight.

Yukon's comment about spam is correct. During the heyday of "bum marketing", EZA was flooded with digital manure for backlinks, and Google slapped them silly.

That said, EZA still has some use. Specifically, it can serve as a portfolio for writers, proving that they can create content that passes EZA's fairly stringent approval process. The "Expert Author" and "Platinum Author" badges don't hurt, either.

If you publish a traditional email newsletter, EZA can be a source of talent. There's still too much crap to go hunting for individual articles, but you may stumble across a writer you like. You can then follow up with them for future work.
