Currently, in the send emails action, all emails are sent using a list of Single Email Messages.
There may be reasons why we should support sending using Mass Email Message, instead-- such as the use of a different system limit when sending Mass Email instead of Single Email.
Mass Email does impose other restrictions, though, such as requiring the use of templates and recipients being valid records instead of just email addresses.
The choice of whether to use Mass Email or Single Email may best be exposed as a configuration option or it may be something we allow the user to choose while interacting with the send emails action. In either case, certain elements of the UI may need to be adjusted according to the requirements of the type of email being sent.
