Privacy and Security: ProtonMail

March 27, 2024 Blog

In today’s digital world, the privacy and security of our communications have never been more crucial. ProtonMail stands as a robust email service solution for those who prioritize safeguarding their personal information.

Today on the ZTalent blog, we’ll delve into ProtonMail to provide a comprehensive understanding of why it has become a preferred choice for millions of users worldwide.


ProtonMail was conceived at the heart of CERN (European Organization for Nuclear Research) in 2013. Guided by Sir Tim Berners-Lee, the inventor of the World Wide Web, a group of scientists and engineers, concerned about increasing online surveillance and the erosion of privacy on the internet, sought to create an email system that could protect users’ information from unauthorized access, including that of email service providers themselves.

The official public launch was in 2014, following a successful crowdfunding campaign that demonstrated the interest and demand for such a service. Since then, ProtonMail has experienced exponential growth.

Features and Design

ProtonMail stands out in the email service landscape for its commitment to security and privacy, incorporating a range of advanced features into an intuitive and user-friendly design. At the core of its security system is end-to-end encryption, ensuring that only the sender and recipient can access the content of messages. This means that not even ProtonMail can read your emails, protecting your privacy even against third-party requests.

Key features include:

ProtonMail offers functions such as self-destructing emails, where users can send messages that are automatically deleted after a set time, enhancing the security of sensitive information, and customizable filters for efficient email management.

ProtonMail’s design also reflects its privacy philosophy; the platform is designed to be resilient against phishing attacks and other deception methods, thanks to measures such as domain verification and two-factor authentication.

Furthermore, the new version of ProtonMail Bridge allows using ProtonMail with email applications like Apple Mail, Outlook, or Thunderbird.

Advantages and Disadvantages


  • Based in Switzerland, ProtonMail benefits from the country’s strict privacy laws, offering robust legal protections to its users, along with end-to-end encryption.
  • It guarantees user anonymity by not requiring personal information for registration.
  • With security measures such as two-factor authentication and data encryption at rest, ProtonMail is resilient to cyber attacks and stands out for not displaying advertisements or tracking user behavior, ensuring privacy respect at all times.


  • The maximum number of emails allowed daily is 150 for the free plan. Business users may need to opt for a paid subscription or resort to other providers for sending bulk emails. For users with a paid subscription, this limit increases to 1,000 emails per day.
  • Secure cloud storage space is only 500 MB, contrasting with other email service providers offering significantly larger or even unlimited data limits. However, those who value privacy and security generally show little interest in storing their files remotely.

Availability and Plans

ProtonMail is accessible worldwide, offering a variety of plans from free to premium. Premium plans offer advanced features such as increased storage, support for custom domains, and access to additional services like Proton VPN and Proton Calendar.

In summary, ProtonMail offers a robust solution for those who value privacy in their digital communications. Features such as end-to-end encryption and an intuitive design set it apart in the market, providing users with a high level of security.
