Using email more securely
Do not use public computers to access email with sensitive information.
If you are not in a safe neighbourhood, use a VPN or Tor anonymity network to encrypt traffic from the user machine to a safer network.
Use privacy-focused email services, and have at least two email addresses, one for private use, and one for public use, (and do not use your own name or other personal information)
GPG, PGP, SMEmail, can be used for end-to-end message encryption.
