This is a bookmarklet used to send multiple Eloqua test emails at once. It uses the XSRF token of an active session to interface with the E9 module that handles the sending of test emails.
Open your web browser of choice. Create a new bookmark. Edit the newly created bookmark and change the source to the contents of "bookmarklet.txt"
Log in to Eloqua as you normally would. Once the main page has loaded, open the bookmark and the Test Sender interface should appear.
