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.
