I never shared my email with anyone. I am not using Binance from desktop very often. Only from my mobile and not every day. I don't know what happened.
Anyway i changed all my passwords.
I had the same notification when i logged in, so the email was not phishing
Check login history
https://www.binance.com/en/my/security/account-activityyou may notice some suspicious sessions.
In the security settings, there are Anti-Phishing Code options, additional security will not hurt.
btw. it is easily possible to send an email even if you are not the owner of the default domain.
