In iOS 11, Apple introduced a new feature that lets you add a quick drawing or sketch to an email message right within the Mail app. It's a simple, easy-to-access feature, but it's a little bit hidden, so you might not know that it exists.
Here's how you can get to the built-in drawing tools in the Mail app on an iPhone or iPad:
- Open up the Mail app.
- Compose a new email or reply to an existing email.
- In the body of the email, tap to bring up the options menu.
- Tap the arrow at the right of the options menu twice.
- Select "Insert Drawing."
That's all there is to it. Once you've selected "Insert Drawing," you'll be taken to a blank screen with a variety of simple drawing tools like a pen, pencil, marker, and eraser, along with a selection of colors to use.
Create your drawing using the provided tools, and when finished, tap the "Done" button and it'll be inserted right into the body of your email.
