10,000 email address is a good number. You can target them through multiple ways. You can upload the entire list along with first name, last name, location, contact number(if available), email id etc. on Facebook and can target them through Facebook and Instagram.
The same can be implemented through LinkedIn as well. But LinkedIn will be bit expensive. You can add a remarketing pixel in the website and they can be targeted through Google as well.
