How can I Monetize french car services database?

Hi there expert team !!!

Hope everybody is going well ...

We have services in France and soon in other European country ( Germany , Spain , Italia , UK ) for owner of car ...

In the database we have contact info of 50k car owner ( Name , Model of car , type of insurance , when he bought the car )

Now we looking for monetizing this huge database ...

Any idea ?

not much coz basically everyone can scrape or extract that info. I suggest you try spamming them with your email offers such is insurance or lead them to a landing page that has your ads on it.
