Marketing through auto responder series is a popular strategy to increase repeat website visits and sales. Here is a popular strategy. 
EZINE EBOOK
Instead of trying to publish a small daily or weekly eZines, try publishing one large monthly eZine (similar to a monthly magazine) as an e-book format delivered via auto responder, preferably an Adobe .pdf file. You could have it made up of a large number of articles per issue and insert regularly featured areas throughout like inspirational quotes, industry tips, favorite sites and advice from the pros. You could also insert full-color graphics, multimedia components like audio / video file links and ads. Then you can charge a monthly rate, with an annual discounted package purchase, and sell advertising spots to sprinkle in your auto responder announcements for each issue and with an informational series to announce your monthly eZine to new prospects.
In summary, by using customized marketing techniques like an eZine eBook, tailored to fit your own products and services, you can reach out and increase your website traffic and sales opportunities. Internet marketing can mean more ways to grow your business.

Stuck in an auto responder rut with only your eZine going out regularly? Get out of the rut with some of these ideas for improvements.
1. Provide back issues of your eZine archives via your auto responder instead of hosting all your archives online. This will give your subscribers and web site visitors easy access to them and offers a chance to include graphics, audio and video and other components all rolled up in .pdf files for quick, easy download.
2. Help with tech issues and publish your entire web site, save it in a pdf file, and load it into an auto responder. Sometimes visitors don't have enough time read your entire site or they lose their Internet connection or time online. So this way, they could print it out and read it offline.
3. You could offer your eBook via an auto responder. Often your visitors won't have to download it or have the software to read it right away, so this way they can take it “to go”.
4. For a handy - -and nice legal - touch, you could include the terms and conditions to purchase transactions and load them into an auto responder that is triggered with each purchase. This could include return policies,
