It is a bit strange. Google suggests that quite a few people had the email but never owned Renaults. Maybe owned one of the brands under their umbrella?
Also think the 3rd party was a financial part of the company are something like that. Why would a financial part of the company have my details if I’m not the customer?
Finally absolutely nothing about it online from Renault themselves. Maybe they rushed the email out and are now locked in talks with the legal eagles to get them to make it a soft landing for them lol
