If you are a tech and privacy enthusiast, you might have heard of Proton, a popular Swiss-based company that offers a lot of privacy-oriented applications under its umbrella, such as Mail, VPN, Drive, and Password Manager.

Today, our focus is on the Proton Mail service, whose desktop app is now available. If you're wondering what the big deal is, let me tell you that Proton Mail uses its own secure protocol to exchange mail from your system to the Proton server.

This protocol prevents you from configuring Proton with other desktop mail clients like Thunderbird or Outlook using SMTP or POP3, so you must only view, send, and manage your emails on the Proton Mail website.

Previously, there wasn't a dedicated desktop app for Proton Mail, so accessing its website was the only option for reading, sending, and managing emails. As you know, a browser is more than just for reading emails, so having a separate desktop app was quite important for instantly accessing your important emails.

Now, with the introduction of this desktop app, you can easily access your Proton Mail from a desktop client instantly on Linux, Windows, and macOS. And if you're on Proton's free plan, you can try the desktop app with a 14-day free trial.

Getting a native desktop notification of new mail has also become accessible. I'll recommend you read the Proton Mail Desktop app introduction page to gain more insight.
