Proton Mail
Free TierYou might be paying for: Paid secure email services
End-to-end encrypted email that nobody can read but you — for no monthly fee.
What you get
- ✓End-to-end encryption
- ✓Swiss privacy jurisdiction
- ✓No data mining
- ✓No ads
What's different from the paid version
Free tier starts at 500 MB but expands to 1 GB by completing Proton's onboarding checklist. Still tight — you'll need to delete old emails regularly or pay to upgrade. Sending encrypted mail to non-Proton users requires them to click a link and enter a password.
Perfect for
Anyone who values email privacy — journalists, activists, or just people who don't want their inbox scanned.
