Julio receives many emails from a healthcare site. He finds them useful, and he wants to save them all in a folder. How can he automate the process of moving all such emails to a particular folder?

Possibly by using a Macro if you are using a client application such as microsoft exchange.

If their email is something like gmail or outlook where it is mainly ran online, then it depends on your provider, from what I know, there is a filtering setting for directing emails to specific categories.
