The Details are important _ Pay special attention to the details. They affect your readers very much. Details like alignment of the texts and the number of lines which your paragraphs include, can make readers bored or can interest them.
The Nameplate and Masthead _ You must have a nameplate including the name of your publication and the date it is published. You should have a masthead too. Both nameplate and masthead are necessary. Your masthead lets people know the name of the author if your newsletter is personal or it says contact information if it's a company newsletter.
