Saw this post after posting:
It seems to be a good workaround and I'm testing it now.
I've implemented a 'reply to human' shortcut with every email the agents send back to clients.
'Reply to human' then triggers another flow, which is a question saying 'type your follow up question'
Then the answer is again sent to the agent with email, including the shortcut again, which continues the cycle.
This is a cool trick but the other trick mentioned in that post is even better: change user attribute from within the email.
Like this, I'd say catch_all and send them to my email. If the email is a help request, then I'll change the user attribute to 'supportticket' and basically kick the bot out. When I'm done, I change the attribute to 'user' by adding a line at the end of my email.
How do I do this? What is the magic line that changes a user attribute from within the email's text?
