Importing from Mail into Keep It

You can use drag and drop messages from Mail to Keep It, and it will import them as standalone email message files that can be viewed in Keep It, with Quick Look, and other apps.

If you are using Finder integration, you can also drag messages to Keep It’s location in the Finder. See here for more information on how to use that.

Some versions of Mail have issues where you may not be able to drag messages to apps other than the Finder. In addition, older versions of Mail can drag multiple messages or conversations. To get around these limitations, you can install an Automator workflow that will appear in the Services menu in Mail. See here for more information:
