Drag and drop to create attachments
The easiest way to attach pictures, movies, documents, or any file to a message composition.
Drag and drop is the easiest and most intuitive way to attach any file or images to a message composition.

- Compose a new message. You can use the New toolbar item, the File > New menu item by replying to a message you received.
- Drag one or more files to the Mailplane window.
- Drop the file. Mailplane will automatically attach the file and upload it.
Drag and drop to the Mailplane app icon

If you wish to start a new message composition and directly attach one or more files to it, you can directly drop your files to the Mailplane application icon.
Tip: Use Command-Tab
If Mailplane is hidden and you like to drop a file one of its windows or on the application icon then try the ⌘⇥ keyboard shortcut while you drag the file.
Drag and drop images

You can also drag and drop images that are not files, for example a picture shown inside a Safari page.
