Compose Mail Mac Markup Tool

Whether you want to annotate an image for work, mark up a photo for fun, or add your signature to a PDF, it’s easy to do with the Mac Mail Markup tool. You have all the basics you need to add shapes, text, signatures, drawings, and more to your email attachments. And, here’s how to use this cool feature.

Attach your file and open Markup

With your Mail app open and the window to compose a new email, just follow these steps:

1) Insert your image or PDF file. You can do this by using the buttons in the compose mail toolbar, dragging and dropping the file from your computer, or clicking File from the main menu and selecting Attach Files.

2) Click the attachment in your message and access the Markup tool. If you have the Markup button in your compose mail toolbar, click it. Otherwise, you can click the arrow on the top right of the file and select Markup.

Note: If you do not see Markup as an option, make sure that you have it enabled. From your Mac menu, click the Apple icon > System Preferences > Extensions. Click Actions and check the box next to Markup.

3) Your attachment will then display in the Markup window where you can begin annotating it.

Once you have your file open in the Markup window, you have many options to annotate it. Starting from the left side of the toolbar, here are the tools:

  • Sketch: Sketch your own shape or text onto the attachment.
  • Draw: Basically the same as Sketch for those who have a Force Touch trackpad on Mac.
  • Shapes: Select a shape, line, or arrow, drag it to where you want it, and resize it if needed.
  • Text: Add any text that you like and move the text box anywhere on the attachment.
  • Sign: If you have an existing signature set up, it will display here. Select it and then move it or resize it. If you do not have a signature set up yet, click Create Signature to make one and add it to the attachment.
  • Shape Style: Change the thickness of shapes, lines, and arrows you add to the attachment.
  • Border Color: Change the color of the shapes, lines, and arrows you insert.
  • Fill Color: Change the color of the inside of a shape.
  • Text Style: Change the font style, size, formatting, alignment, and color for text you add.

When you finish marking up your image or PDF, click Done. The annotated file will pop back into your email with all of your changes.
