Direct Mail supports all of Apple Mail's templates (or "stationery", in Apple Mail terminology). By default, all of your Apple Mail stationery should automatically appear in Direct Mail's template chooser—you do not need to import it manually.
If you have Apple Mail stationery that does not automatically appear in Direct Mail, you can import it manually. Your computer must be running macOS 10.8 (Mountain Lion) or newer. Here's how:
- Open Direct Mail
- Choose Help > Import Stationery from Apple Mail
Your Apple Mail stationery will be imported into Direct Mail and will appear in the template chooser.
