Option 1

Gmail

Most-used email globally; tight Google integrations; Gemini AI.

Best for

Google Workspace users, AI-assisted email (Gemini in Gmail), 15GB free storage.

Pros

  • 15GB free; $2-10/mo upgrades for storage
  • Best AI integration (Gemini in Gmail)
  • Tight Google Calendar, Drive, Meet, Docs integration
  • Best spam filtering
  • Massive third-party app ecosystem

Cons

  • Google scans email content for features (no longer for ads since 2017, but for ML training)
  • Encryption only in transit + at rest, NOT end-to-end
  • Lock-in to Google ecosystem

Option 2

Proton Mail

End-to-end encrypted email; Switzerland-based.

Best for

Privacy-conscious users, journalists, activists, anyone wanting E2EE.

Pros

  • End-to-end encryption between Proton users
  • PGP support for non-Proton users
  • Zero-access encryption (Proton can't read your inbox)
  • Switzerland-based (strong privacy laws)
  • Bundle: Mail + VPN + Drive + Pass + Calendar ($10-20/mo)

Cons

  • Smaller storage on free tier (1GB free, $5-10/mo for more)
  • Limited AI features (less than Gmail)
  • Smaller third-party app ecosystem
  • E2EE only between Proton users by default; non-Proton requires PGP setup

The verdict

Privacy-conscious or work with sensitive material → Proton. Google ecosystem user, want AI features in email → Gmail. Many people use both — Proton for personal/sensitive, Gmail for non-sensitive work. The Proton bundle (Mail + VPN + Drive + Pass) is a good privacy-suite alternative to Google.
