The California CCPA makes this much easier than it used-to be. Find the company's website. They'll have a "Do Not Sell" link on the home page or at least in the Privacy Policy it'll say California Privacy Rights. They'll have an e-mail address or a web form to fill out to request they delete your information from their system.

Bit of a hassle to chase each company that's mailing you, but it works to eliminate any annoyances.
