How do I verify my email address?

First off, I am not rada449fef90. I am rada44. I am asking about verifying my email address because I got an email from team@repairpal.com instructing to do so before I could get a response to my question. The instruction was at the top of the web page with my question. Since there seems to be confusion as to who I am, let me restate my question. The manual for my brand new 2017 Mazda 3 2.5 Touring hatchback says not to leave anything plugged into the USB port when you turn to car off because it could cause damage. Since a flash drive is totally passive, I am asking if anybody knows if this applies to it?
