If you know the publication you want to pitch, next you should find the section or department you want to pitch, so you know what to reference when you send an email to the editor. It shows you know the publication and have done your homework!
For instance, rather than vaguely pitching a story for the "Health" section of the New York Times, you look much smarter when you say you'd like to pitch a story for the "Well" section, or even more specifically, the "Well" subsection focused on the mind.
Join me for several examples as I page through magazines and online sites to show you where the masthead and staff boxes are to find those sections, editor names and editor emails. With online sites, you may find bios as well that give you details you can mention in the email.

New York Times Well section (and the Mind subsection)
Slate.com's masthead (and the great bios!)
