How do I lookup an email in a contact list and set it as embedded date so I can create an action?

Hello. I have a contact list already uploaded with names and emails. One of the questions in my survey is a dropdown with the list of names. Is there a way I can use the answer from that dropdown to lookup the email and set it as embedded data so I can pipe it into an action later? This will save me from creating 30 actions (1 for each email).
