Choose a random live Triggered Email from the given folder, and queue it to the specified recipient for immediate send
The system uses a weighted random choice, so that over the course of many sends, there is even distribution amongst all live Triggered Emails in the folder. Only Triggered Emails directly in the target folder are used; child folders are not used.
Will fail if no Triggered Emails in the folder have approved
status.
