Emails can be saved as files for backup or sharing with other apps.

To save an email as an email file, select "Save as email file" from the action menu (circle with 3 dots button). Then you can choose the location of the new email file, such as a local file location or a cloud server or your mac or PC using WePrint (View).
You can view saved email files in the 'Files' screen in the left side panel.
