How do I get a nodes authors email address within views? I have a view that list nodes of a certain type. These nodes are created by different users.

In my view, how would I get the email address of the creator of the particular node (I will pass this email to a webform)?

Go to admin/structure/views and edit your view
Under advanced section tab add relationship Content: Author 
Add the relationship.
