Above the fold
The part of an email message or Web page that is visible without scrolling. Material in this area is considered more valuable because the reader sees it first. Refers to a printing term for the top half of a newspaper above the fold. Unlike a newspaper, email and Web page fold locations aren't predictable. Your fold may be affected by the users preview pane, monitor-size, monitor resolution, any headers placed by email programs such as Hotmail, etc.
