Oooh, interesting. I got the same email but mine didn't have that pointed question, so I figured it was boilerplate and ignored it.
Maybe you can wait it out a couple of days and see if it ships anyway? Or, maybe you can respond in the same professional tone, "Hi, thank you for reaching out. I am an independent researcher and you may list my first and last name as business name for purposes of the account."...? It's hard to tell if this is just a standard letter he's sending to everyone, or if the influx of orders has them sat upright.
