Out of the blue. I am very careful about what I sign up for, I don’t have a car nor can I find any previous emails from the person involved (going back ten years). There’s no chance I signed up to a mailing list for a car accessory — and just in case I had somehow subscribed (maybe through another product they offer) I asked how they got my email address and they didn’t respond which is a tell tale sign of a spammer. My email address was included in a database leak from Kickstarter in 2014, so I am almost certain they have been spamming everybody from the Kickstarter database leak.
