List Send lets users populate a list of recipients anywhere from a small group to a list of up to 500 recipients who are records in Salesforce (Contacts or Leads). You can add this list To/Cc/Bcc fields and use templates or compose your own email without going anywhere outside the Sidebar, and with just a few clicks. List Send leverages List Views on Salesforce to enable this faster communication. More info in this KB article on How to use List Send.
