Hi John! Welcome to Emma, and I can definitely help here.
Google Maps uses iframe to embed their maps; however, iframe code isn't supported within the Emma editor, since that code is intended for the website environment. Not to worry! You can easily take a screenshot of the desired map, then link that image to the Google Maps URL -- while viewing the location in Google Maps, you can click the "Share" icon and grab that URL. More on linking to images here.
Also, I wanted to pass along this helpful link to help you get started with your new account, which includes information about our Resource Center, webinars, and Emma 101.
Just give me a shout if you have any follow-up questions here, John.
