Sometimes you may want to send a newsletter with only one page. Furthermore, you may want to send the contents of that page in an email to your subscribers, instead of a summary (which is what's normally sent).
To send a single page newsletter, first create a new newsletter issue and disable the cover page. Then ensure your newsletter only has one page.
iNewsletter will automatically send the full page as an email to your subscribers when you publish the newsletter, instead of sending a summary of your full newsletter.
