Electronic magazine are known as ezine (e-zines). Some ezines are simply electronic versions of existing print magazines, whereas others exist only in their digital format. Most ezines are advertiser-supported but a few charge a subscription. eZines letters are sent via email containing tips, information, reviews and tests. They cover every imaginable subject, everything. They are sent to each recipient via email.

Your Resource Box would include a brief description of your business or web site (3 to 4 lines is typical) and your URL.
To receive these e-zines, people chose to subscribe. They therefore are highly qualified leads. By submitting articles with a link to your site, you can generate a lot of traffic.
