Illustration of Proton Mail in iOS

If you’re an iPhone or iPad user, you can now set Proton Mail(new window) as your default email app in the latest version of iOS. This is a welcome decision from Apple to allow users to choose their preferred email service, and means that “mailto” links can now open in Proton Mail instead of Apple’s Mail app. 

Although this is a small change, it represents a win for privacy because you can now more meaningfully control how you send and receive data on your own device. Here we talk about why this matters and, toward the bottom, how you can change your default mail app to Proton Mail.

What this means for Proton users

iOS has always been a “walled garden” that Apple keeps under tight control. One of the ways it has done this is to prevent third-party apps that compete with its own apps from being set as the default apps used by iOS.

The result was that most iOS users take the path of least resistance and settle for using Mail as their email client and Safari as their browser. In this way, Apple ensures most of its users stay within the Apple ecosystem, including using lucrative premium services, such as Apple TV, Apple Music, iTunes, and iCloud.

This has been hugely profitable(new window) for Apple but is hostile to the interest of its customers. Recently, however, people have begun to push back. Following efforts from developers including Proton(new window), Apple has made moves to placate critics, including allowing users to change their default email client and browser starting with iOS 14. 

Although a relatively minor concession for Apple, this is great news for Proton Mail users. You can now send secure end-to-end encrypted messages by default, using an open source app and a service that never spies on you or shares your data with third parties.
