In-depth review
In a world where privacy matters more than ever, Tuta Mail and Proton Mail stand out as top encrypted, private email providers for individuals and businesses. But Tuta Mail goes further than Proton Mail by encrypting more data, ensuring stronger privacy, and offering a more transparent, user-friendly experience. Both free secure email services protect your online communication like emails, calendars and contacts with end-to-end encryption, but only Tuta already uses quantum-safe algorithms for this. Thanks to the automatic encryption and user-friendly interfaces, these two private email providers are setting the standard.
Proton Mail describes itself as “Secure email with absolutely no compromises, brought to you by MIT and CERN scientists”; it is based in Switzerland and has more than 100 million users. Many email providers claim to be good alternatives to Proton Mail, but only Tuta Mail is encrypted like Proton, making it Proton Mail’s number one rival. Tuta Mail is built in Germany, a country with some of the best data protection laws, has more than 10 million users and describes itself as “the world’s first end-to-end encrypted mail service that encrypts the entire mailbox. With its unique open source technology Tuta fights for privacy and freedom of speech online.”
Let’s check in detail which of the two is better, Proton Mail or Tuta Mail!
暗号化
Both Proton Mail and Tuta are privacy-focused email providers that offer end-to-end encryption for all emails for free. Both enable everybody to use shared passwords for encrypting emails sent to recipients that don’t have an email address with an encrypted email provider. One major differentiation here is that in Tuta Mail external recipients can access the entire email thread via the shared password while recipients of encrypted messages from its rival Proton Mail are limited to just seeing one message.
In addition, there are quite important differences in the encryption methods used. Proton Mail uses PGP encryption, which lacks important requirements that the Proton replacement Tuta is able to fix. Tuta Mail encrypts not just bodies and attachments of emails, but also the subject line, which can contain very sensitive information. Additionally, Tuta already uses a hybrid encryption protocol with traditional algorithms ((AES/ECC)) and new quantum-secure algorithms (ML-KEM). Thus, only Tuta can protect your messages from the threat of “Harvest Now, Decrypt Later”. As Tuta does not use PGP, it can encrypt much more data than Proton Mail such as the entire address book and calendar metadata like calendar notifications. Tuta is the only email service that automatically encrypts all of this data.
Email security
Tuta and Proton Mail both prioritize user security and privacy over profits, unlike older generation free email providers like Gmail, Yahoo Mail and Outlook. People choose to create email addresses with these two private mail services to get rid of Big Tech tracking and personalized ads. Tuta excels in this regard as it pays more attention to details, particularly when it comes to respecting user privacy. For instance, Proton email uses some integrations with closed-source third-party services, including Google push notifications while Tuta has published its Android app on F-Droid, making it one of the few email apps available with ZERO ties to Google services.
オープンソース
Tuta has a strong focus on open source. All client code of all Tuta apps, email, calendar, free email desktop clients are published under GPLv3 license on GitHub. While Proton Mail claims on their website that “all Proton apps are open source”, Proton’s GitHub page does not show the latest updates. In addition, Proton’s Calendar and Proton’s paid desktop clients are not being updated on GitHub anymore which makes it impossible to know what code exactly runs in these clients. Only code that is open for public inspections like Tuta’s entire client code can be reviewed by others to make sure there are no backdoors or vulnerabilities.
Location
Proton Mail and Tuta Mail use secure servers located in Europe; Protonmail in Switzerland, Germany and Norway, and Tuta Mail in Germany. But Proton also has secondary offices in the US, one of the Five Eyes countries.
ビジネスプランの機能
Tuta and Proton Mail both offer business-focused plans, with secure business email and calendar, multiple custom email domains, multiple alias addresses, email import, labels and inbox rules. Only Tuta allows you to create an unlimited number of custom domain email addresses, have an unlimited number of fully encrypted calendars and a plan with a whitelabel version, while only Proton email business plans include a VPN service.
持続可能性
While Proton Mail doesn’t have any sustainability initiative as of yet, Tuta uses 100% renewable electricity for all its servers as well as its offices. When you use Tuta as your encrypted mail provider, your emails have close to zero environmental effect. A private, secure and encrypted email service that is also the most sustainable option is a choice you can feel good about!
料金
The real difference between Proton vs Tuta Mail becomes obvious when looking at features within each plan: Both Tuta and Proton Mail operate on a freemium model, offering free and paid versions of their email service. Tuta paid plans are more affordable and include more features compared to ProtonMail’s.
In Tuta’s Revolutionary plan (€3.60/mth), you get 20 GB of storage, 3 custom domains, 15 email addresses and an unlimited number of custom domain email addresses while in Proton’s Mail Plus (€4.99/mth) plan, you get 15 GB of storage, 1 custom domain and 10 email addresses. The Tuta free version includes 1 GB of storage, while Proton’s free version includes 500 MB of storage
