How Runbox compares to privacy-focused email providers Proton, Tuta, Fastmail, Posteo, and Mailbox — an honest look at jurisdiction, encryption, and AI use.

Thanks for the rundown and reminder. It’s been a few years since I looked at Runbox so might be worth another look. Comparison on their website interesting - https://runbox.com/features/runbox-compared/ Edit: this one more detailed Runbox vs Proton, Tuta, Fastmail, Posteo & Mailbox

Runbox: “What follows is an honest attempt at comparing Runbox…” Also Runbox: It goes without saying that Mailvelope works with all these services, just like it does with Runbox. And the subject line isn’t covered on Runbox or on Proton. Maybe it’s just me, but I’d avoid talking about honesty on a page that also has a standard biased comparison with competitors. It looks like there are plenty of these “generic” email providers with small differences. Infomaniak is similar but cheaper, Codamail bundles an alias service with email, iCloud more secure, etc.

How about Purelymail? Dirt cheap, good for custom domains, and re: security: purelymail.com ### Security | Purelymail

I asked similar question to them. I wonder if they will copy and paste and send the same responses. May I recommend that we move this comment to the Mailbox thread? The one about removing it.

https://www.trustpilot.com/review/runbox.com I know Trust Pilot doesn’t always provide the most realistic reviews, but runbox has 1.9 stars and most of them are from 2026… Protonmail has 2.1, Tuta 3.5 and mailbox.org 4.2 I don’t know what to say, since I have contacted both mailbox.org and posteo and I haven’t yet received a reply in 4 days. Pretty disappointing…

Reposted from: Question about Runbox - #7 by Sorge Got a response from mailbox.org: 1. **SPF/DKIM/DMARC:** We have significantly improved our mail infrastructure since then and have not received recent reports of similar issues. However, we cannot guarantee that every message failing these checks will automatically be rejected or moved to spam. 2. **Password reset and 2FA:** This behavior is related to the integration of Keycloak with our two-factor authentication system. Once your password has been reset, you will need to set up 2FA again to restore the additional layer of protection. 3. **YubiKey and passkeys:** FIDO2/WebAuthn security keys and passkeys are not yet supported with Login 2.0, but support is planned for the future. We currently have no confirmed release date. 4. **Missed payments:** We send three reminders before your subscription expires, giving you time to renew your account and avoid service interruptions. We recommend renewing promptly, as account restrictions may apply after expiration.
