What do I have to do to keep from getting spam and junk e-mails?

About 2 or 3 months ago I mistakenly got involved with some fly-by-night company that forced me to take LOADS of spam e-mails!! First, I started sending them to the spam folder but, they kept coming! Then, I discovered a way to block them so, I do that every time I get them but, I STILL get them!! About 2 weeks ago, I cleaned out the cookies and cache hoping that'd get rid of them but I'm STILL getting them!!! Ads for credit cards, window and roof replacements, insurance, ozempic and who knows what other shit they keep throwing at me!!
