Proton Mail Email Receiving Settings
Proton Mail also supports IMAP settings in addition to SMTP. Thus, users must also know the necessary IMAP settings to set up an email account, which allows it to send notification emails to any mail address you provide. Plus, it will notify you when messages arrive in your Proton Mail inbox and custom folders.
💡 Note: Proton Mail does not support POP3. IMAP is supported only through the Proton Mail Bridge app, and it provides encrypted syncing across devices.

Key Points to Remember for Proton Mail
The Proton Mail Bridge app allows you to import and export email with relative ease.
💡 Note: The Bridge software is presently only available to Proton Mail subscribers who have paid for the service.
Proton Mail Bridge is a program that initiates the encryption and decryption of your messages as they enter and leave your computer. Moreover, the Proton Mail Bridge lets you fully integrate your Proton Mail 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 Proton Mail account, as well as do full-text searches on your Proton Mail 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 Proton Mail email accounts but will be helpful for decluttering the other IMAP-based email accounts you may have.
Although Proton Mail 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.
Setting Up Proton Mail on iPhone
To use Proton Mail on iPhone, you can download the Proton Mail app directly from the App Store. IMAP/SMTP configuration is not supported directly on mobile—Bridge works only on desktop. However, Proton Mail's iOS app offers native encrypted access with upcoming features like offline mode and advanced search.
