Thanks for the information, and any trigger words you would recommend adding that would mess this system up and require an actual human to look at the email?
Your email should go like this:
"To Whom It May Concern:
I have some questions about my trip.
Please get back to me at your earliest convenience.
It should be vague enough to warrant a human response. Also another tip is that when ever they reply to you there should be a line at the very top of the body of email. Put your reply if you need to over that line so It can pop up again on their inbox.
