Hi!
I'm trying to automate my project so that when we receive an email request from address X then the analyst responsible for that customer will answer him/her.
I want to automate the process by assigning specific customers to a particular agent. Let's suppose, if the requestor/email address is X then assign to agent 1, if the requestor/email address Y then assign to agent 2.
Problem is in the automation it won't let me pick an external address, it appears as "No option"

What can I do to add external customers to this automation?
Thanks!
