How to Add a Quick Drawing or Sketch to an Email in the Mail App in iOS 11

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:

1. Open up the Mail app.
2. Compose a new email or reply to an existing email.
3. In the body of the email, tap to bring up the options menu.
4. Tap the arrow at the right of the options menu twice.
5. 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.
