Can someone scam me just by knowing my email address?
Having your email alone gives scammers limited but real power — including phishing, credential stuffing, and spam — though not direct account access.

Explanation
Your email address is effectively your online identity. While knowing it alone doesn't give a scammer access to your accounts, they can use it to: send targeted phishing emails that appear personalised; try it against leaked password databases in credential-stuffing attacks; enroll it in spam campaigns; register it on services to trigger verification emails; and impersonate you to your contacts using spoofing. If your email address appears in a data breach (check free services like HaveIBeenPwned), change the password for that account and any accounts where you reused the same password. Use a unique password for every account and enable two-factor authentication.
The email account itself deserves the strongest protection you have, because it is the master key to everything else: password resets for banking, shopping, and social accounts all flow through your inbox. An attacker who gets into the email doesn't need your other passwords — they can reset them. That is why the priority order is clear: your email password should be unique and strong, two-factor authentication should be enabled there first, and recovery details (backup email, phone number) should be checked periodically for anything you didn't add.
Exposure also accumulates quietly over time. Every service you register with becomes another place your address can leak from, which is why segmenting — one address for important accounts, another for shopping and newsletters, or aliasing features where your provider offers them — pays off. It limits how much of your digital life any single breach can map, and makes phishing easier to spot when a 'bank' email arrives at your shopping-only address.

Frequently asked questions
Should I give out a different email address for online shopping?
Yes — using a secondary or disposable email address for shopping, newsletters, and non-critical accounts helps contain the blast radius of any breach.
My email was in a breach — do I need a new address?
Usually not. Change the password for the breached service and anywhere it was reused, enable two-factor authentication, and expect more phishing to that address. A new email is only worth the disruption if the account itself was taken over or spam becomes unmanageable.
