Hi, since the Query can retrieve multiple results (even though your filter may only ever give you one) you will need to display the result(s) in a prompt and response of type multiple-options, and have the user pick the record to use. Since you will only
have 1 result, they won't even need to select anything as it will default to the first item in the collection.
Once you have the prompt/response you can use the response in your from lookup.
If you have a page before the send email step, you could just tack it onto the bottom of that page.
Edit: It would be a cool feature though if you could have like a First or Default option for directly setting a lookup from the query results.
Hope that helps
Paul
