ProtonMail: Privacy-First, Now Cleaner Too
ProtonMail already encrypts your messages and protects your identity. But email cleanup still requires manual effort—unless you use Clean Email. While Clean Email doesn’t access encrypted content, it still helps manage metadata-based cleanup like sender rules, sizes, and read status.
You can use Auto Clean to archive or delete older emails based on age, even if they’re encrypted.
And since ProtonMail doesn’t show traditional unsubscribe links, Clean Email’s Unsubscriber can help identify mailing lists and reduce overload.
ProtonMail users often juggle multiple aliases—Smart Folders and Group by Sender help you clean across all aliases more efficiently.
With Clean Email, you get productivity and peace of mind. It’s one of the few tools designed with your privacy in mind that still delivers serious time-saving results.
Key Points to Remember for ProtonMail
The ProtonMail Bridge app allows you to import and export email with relative ease.
💡 Note: The Bridge software is presently only available to ProtonMail subscribers who have paid for the service.
ProtonMail Bridge is a program that initiates the encryption and decryption of your messages as they enter and leave your computer. Moreover, the ProtonMail Bridge lets you fully integrate your ProtonMail account with most IMAP and SMTP clients, including Microsoft Outlook, Mozilla Thunderbird, and Apple Mail.
The Bridge also allows you to import emails from other email accounts connected to the same client into your ProtonMail account, as well as do full-text searches on your ProtonMail emails.
💡 Note: If you are looking for a secure email management app for your second email account (Gmail, Outlook, iCloud, etc.), the Clean Email app will help you organize and clean your emails automatically. The app doesn't collect or share user data with any third parties. The app doesn't work with ProtonMail but will be helpful for decluttering the other IMAP-based email accounts you may have.
Although ProtonMail does not support POP3, Bridge addresses this issue as it allows users to download all of their mail into their clients and then export it.
Ultimately, ProtonMail is a more recent email service that focuses on the security and privacy of email users on top of a competitive email service. They encrypt all email messages and store them on extremely secure servers. It has gained some popularity in recent months due to its focus on security and new innovative approach to email messaging.
