Weaknesses of traditional email
Traditional email is not encrypted by default, so your messages can be intercepted and read in transit. Email is also the main route for phishing, malware and social engineering attacks. Even well-known email services scan your messages for targeted advertising.
Choosing a secure email provider
ProtonMail offers end-to-end encryption and is based in Switzerland, which has strict data protection laws. Tutanota offers similar features with an open-source model. Even if you stay with Gmail or Outlook, turn on two-factor authentication and review your security settings regularly.
Recognizing and avoiding phishing
In phishing, attackers pose as legitimate organizations to steal your information. Always check the sender's full address, be wary of urgent requests, do not click suspicious links, and never give your login details by email.
PGP/GPG encryption
For truly sensitive communications, use PGP (Pretty Good Privacy) or GPG (GNU Privacy Guard). These tools encrypt your emails end to end. They are harder to set up, but they give you the strongest security for your most important messages.
Email security best practices
Do not reuse your email password on other services. Turn on two-factor authentication. Be careful with attachments, even from people you know. Use email aliases when you sign up for services, to protect your main address. Clean out your inbox regularly and delete emails that contain sensitive information.
