In a Workflow it is simple to add a Condition based on the Field that a Ticket was sent To a particular Email Channel. This creates a condition called something like ‘Ticket fields.to email’ etc

I want to use the To Email field in an Expression Builder, I cannot find the placeholder to use. I have searched the options in the Workflow user interface and the List of Dynamic Placeholders article, but I find nothing. 

I tried guessing the Placeholder syntax, using the dialog shown above for the first and the Ticket API fields for the second

{{ticket.to_email}}

{{ticket.to_emails}}

but neither of these returned the data in the Ticket Field ‘To Email’.

Does anybody have any suggestions?
