I received their spam, reported it to mailchimp (their provider) and was told that they were suspended.

was it out of the blue or did you sign up for something at some point?

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.

the kickstarter leak makes sense. that's very unethical behavior that should not be rewarded.

I received the same spam.
