Basic and easy internet precautions are not "register and run a domain and host your mail yourself". Basic and easy precautions are don't reuse passwords/use a password manager, use a reputable email provider, enable 2fa with totp, and dont click links from your emails

Because they're low risk high reward, easy to set up, and you only need to make one mistake.
