An eZine is a electronically delivered magazine, newsletter, that is distributed by e-mail over the Internet.  It is usually longer than an newsletter.

Sometimes an eZine is delivered in its entirety within an e-mail. 

Sometimes an e-mail announcement is forwarded with a hyperlink to the web site that contains the eZine.

Sometimes a teaser e-mail is sent that lists all the contents/headings including in that issue with a hyperlink to a web site where the full article is displayed. 

Our eZines are sent as teaser e-mails.  They include a list of the contents included with a hyperlink to the full eZine.  We found this method to benefit our readers because:

(1)  They don't weight down our reader's e-mail inboxes.
(2)  Our readers can quickly decide if there is something of interest in the issue.
(3)  It has less chance to be blocked as spam.
