Key points
- TLS encrypts email in transit between servers
- Encryption at rest protects stored mail
- E2EE is stronger but rarer (Proton-style)
- No ads/no-data-selling matters as much as encryption
How to do it
- Confirm your provider uses TLS on every connection
- Check 'encrypted in transit' indicators
- Understand at-rest encryption
- Decide if E2EE is required for your industry
Common mistakes
- Assuming all email is E2EE by default
- Ignoring the privacy policy (ads/data selling)
- Not encrypting attachments for sensitive docs
