In lists of information that contain email addresses, it's now possible to send a quick, ad-hoc email campaign to the people you see listed. This means that you can build complex reports with filtering and customization, and quickly send them an email. This feature is available for several modules such as People, Companies, Billing, Blog, News and Leads. Just pull down the Reports menu to the top-right of the table and select "Email Campaign." You'll be taken to the Email Marketing Module, and the list of people will have already been added to the distribution list.
