Customer Service With Your Email Signature

I am starting to republish my first book from 2003, You Need To Be A Little Crazy: The Truth About Starting and Growing Your Business with Booksurge. As I was communicating with the sale rep, April during the selling process, I noticed her email signature said:

How’s My Driving?
Did this answer appropriately address your question(s)?
If Yes; send an email to this address:  salesteam701@booksurge.com      
1 – Excellent – (explanation optional)          
If No; send an email to this address:   salesteam702@booksurge.com
2 – Unsatisfactory (please explain)

I loved it. How simple and yet so effective. I felt it instantly gave me permission to give them feedback when things went well or went things went poorly. I felt there was a way I could communicate so that someone would be listening. It made me want to do business with them.

Many times, this is all our customers want- an opportunity to be listened. Is that so hard?
