Online data leaks has been one of the major setbacks on the internet. Many of these stolen information are also being sold over in the dark web. But there are some platforms where you can check if information such as your email has been pawned. These platforms won't stop data breach but they will help you in preventing future scams usually sent on email such as phishing sites.
Check for breaches:
https://haveibeenpwned.com/
https://monitor.firefox.com/
https://spycloud.com/
Results may vary in those three sites but if in case your email has been breached/pawned, take the necessary steps to protect yourself. You can change your password immediately or you can change your main email and ditch the compromised one.
