The email messages have already been synchronized with the Gmail application; so, Gmail takes us directly to the "Primary" email list. However, there is a VisiHow video on how to add an account to the Gmail application.
We tap the button in the top-right corner to compose a new message
No matter whether we are responding to someone or composing a new message, we can open the email message; and it will have a very similar layout to the one shown in the video. There is a VisiHow video with exact instructions on how to compose an email message.
We will see that Gmail will be attaching our new PNG-format scribble. Gmail will say, "Attaching..." and there will be a circle rotating in the very top-left corner. The circle will disappear once the scribble has been attached. We will also see that our attachment has been attached by the word "Attached."
This is a VisiHow video. This is a tutorial on how to add a scribble attachment to the Gmail application on the iPhone 6. If you have any questions or comments, feel free to add them to the section below. We'll do our best to get back to you.
