I was able to solve this by putting my list [subject-list]
shortcode in the To: field in Mail section.
Here’s a little more detail:
My Form with Pick List containing Pipes for mail recipients:
<p>Subject (required)<br />
[select* subject-list include_blank "Customer Service | Customer Service <[email protected]>" "Sales & Business Development | Sales Team <[email protected]>" "Media | Person One <[email protected]>, Person Two <[email protected]>, Person Three <[email protected]>," "Client Services | Person One <[email protected]>, Person Two <[email protected]>, Person Three <[email protected]>, Person Four <[email protected]>"] </p>
I then just set the To: field to [subject-list]
I used [_raw_subject-list]
in the Subject field of the Mail template to help the recipient understand the context of the mail they were receiving.
