Understanding why you receive spam helps you stop it:

Data Breaches: Your email was leaked when a company got hacked (check at HaveIBeenPwned.com)
Website Signups: Companies sell your email to advertisers and data brokers
Email Harvesting: Bots scrape publicly visible email addresses from websites, forums, and social media
Purchased Lists: Spammers buy bulk email lists from the dark web
Reply/Unsubscribe Traps: Some spam unsubscribe links actually confirm your email is active, increasing spam
