John August gives some pointers on appropriate email addresses in his always awesome blog. The blog is a great read for anyone who likes good writing and the occasional nerdery, even if you don’t aspire to be the next great screenwriter (August is a screenwriter probably best know for “Charlie and the Chocolate factory,” and “Charlie’s Angels”).
Which of these people do you expect has a website? Which do you suspect clicks a lot of animated banner ads? Which ones do you anticipate having the most succinct, well-written message?
True for just about anyone who wants to be taken seriously doing anything.
