Pro Tips

To maximize secure email benefits, enable two-factor authentication immediately upon setup to prevent unauthorized access. Regularly update passwords and use alias addresses for sign-ups to minimize spam exposure.

Combine your secure email with a VPN for layered protection, especially on public networks. Migrate data in batches to avoid disruptions, and test encryption by sending self-messages.

For businesses, choose providers with compliance certifications matching your industry. Monitor login attempts and set up notifications for suspicious activity. Use password managers integrated with your email for secure credential storage.

Verify open-source code if available to ensure no backdoors; this builds trust in the provider’s claims.
Opt for providers in Europe for stronger privacy laws; avoid those in Five Eyes countries if concerned about surveillance.
Test customer support responsiveness before committing; reliable help is crucial during issues.
Backup encrypted data regularly using provider tools to prevent loss.
Educate team members on phishing recognition; secure email alone isn’t foolproof.
Explore bundles with storage or calendars to consolidate services and save costs.
Use self-destructing messages for sensitive info to limit exposure time.
Monitor transparency reports for warrant canaries indicating government requests.
