How do I connect my OnMail address to a third-party email app?

OnMail does not have support for using your account with other email applications, such as Apple Mail, Outlook, etc.

Since we have created OnMail using some sophisticated technology, these accounts can't be used with standard IMAP email apps. That said, you are able to use your OnMail account with our own app on iOS and Android, as well as Edison Mail, which is available on the Google Play Store, as well as Apple's App Store for iOS and macOS, and the Microsoft Store for Windows devices.
