This is probably one of the most important aspects of an email client that’s missing elsewhere. Once your email accounts have been set up, all you need to do is to log into your Newton account on a new device, and all the email accounts will already be there. But with Newton, you need to configure your accounts only once. Being a cross-platform app, one of the annoyances of setting up any email client would be to have to set up your multiple accounts repeatedly on all the devices.
