If you use the Mail app regularly, you're used to archiving or flagging emails for later. But what if you want to save a particular message for future reference in the Notes app? Well, there's a work-around for that!

The Notes app has built-in PDF support, so if you add a PDF to a note, it will appear just like an image. This means you can export an email as a PDF and add it to the Notes app.

This can be especially handy if you're planning a trip. You can export all your receipts and confirmations from the Mail app as PDFs, and then add them to the Notes app. From there, you can access them on all your devices, even when you're offline.

Open the Finder app and locate the PDF you just exported.

Click and hold on the PDF, and then switch to the Notes app. Hold your cursor over the blank area in the new note, and then release it.

Drag the PDF from Finder to the Notes app

The PDF drops into the Notes app. By default, the Notes app shows the PDF as a full image. If you just want to see a small preview, right-click the PDF, and then click "View as Small Images."

Click on View as Small Images

The Notes app only shows you the first page of the PDF in the note. Double-click the PDF image to open it in the Preview app.

However, Quick Look is better. To open a PDF in Quick Look, click the PDF and press the Spacebar. The Quick Look window will show you all the pages in the PDF.
