Email continues to be a relevant tool, both in business and everyday life. It is essential for business correspondence, exchanging documents, registering accounts, and authorizing the majority of services and applications. Additionally, there is a growing societal demand for confidential and secure information exchange. Many are aware of the extensive surveillance conducted by Google, Apple, and Microsoft. Secure, encrypted cloud storage is crucial for the safekeeping of personal or corporate information.
Secure mail ProtonMail
ProtonMail has been in operation for nearly ten years. Its strict no-logs policy and use of end-to-end encryption are at the heart of its success. The fact that it is an open-source service creates a high level of trust among users. Additional security measures include storing all of the company’s servers one kilometer underground.
To enhance security, it is recommended to make use of the encrypted messaging functionality available to ProtonMail users. A notable advantage is that ProtonMail offers a free version with up to 500 MB of storage, allowing users to familiarize themselves with the service before opting for full access. The free version is limited not only in storage size but also in the number of messages, allowing no more than 150 per day.
The service offers a functional web client as well as mobile applications for iOS and Android. Additionally, users can create up to 10 nicknames for “one-time” use when registering on third-party resources.
Secure anonymous mail Tutanota
This service is designed to work on popular platforms such as Windows, Mac, iOS, and Android. According to the project website and GitHub statistics, it has more than two million clients.

Tutanota encrypts not only the content of the emails but also the sender and recipient names, as well as the subject line. It supports two-factor authentication, allowing users to choose between TOTP (authentication apps) and U2F (YubiKey).
The project offers a free version with a one gigabyte memory limit, as well as paid plans.
