Where each one fits.

We won’t pretend Rythm wins on every dimension. Here is the honest map.

When Proton Mail is the right choice

  • You want end-to-end encrypted email between you and other Proton users.
    Proton Mail is built around encryption-at-rest and end-to-end encryption between Proton accounts. Rythm does not change how your email is encrypted.
  • You want to leave Gmail or Outlook entirely.
    If switching provider is the goal, Proton (or another privacy-first provider) is the right shape. Rythm assumes you are staying on Gmail or Outlook.

When Rythm is the right choice

  • You want to keep your existing email address.
    Most professional contacts already know your Gmail or Outlook address. Rythm protects the inbox you already have, with no migration.
  • Your problem is strangers at the door, not encryption.
    Rythm is a known-or-pay gate. Senders you know walk in; everyone else pays the cover or waits for review. Encryption is a separate concern.
  • You want unknown-sender email to settle into income.
    When a stranger pays the cover charge, the money goes to your own wallet. Email providers, including Proton, have no equivalent.
