If you scroll down to the bottom of your dashboard, you will see a list of the ten most recent emails and actions you've created, along with buttons to quickly edit and manage each of them.
If you want to see a list of all of your emails, actions, or reports beyond the first ten or duplicate any previous email, action, or report, click the "View All of Your Emails," "View All of Your Reports," or "View All of Your Actions" links at the bottom of each column to see a full list, as well as topline statistics, quick duplicate buttons, and manage links.
