Creating a saved search for all company contacts

Hi - I’m a little stuck on how to create a saved search (so I can send a broadcast) for all of my corporate clients. I have them all set up as Companies; with a linked contact. There is only an email address in the Company file if the company has a generic email (eg inquiries@ blahblah.com) Otherwise the email address I would want to use is the linked contact’s email. Is there a way of creating a search of all the linked contacts who are attached to a company? I can’t immediately see how to do it. Thank you!
