Embed a google map using an IFRAME into my autoresponder email

I was able to set up my autoresponder form just fine, and even was able to embed the google map using an IFRAME.  But when I tested the email the map does not show.  It is just a big blank space.  Does this mean that an embedded IFRAME is not supported in the email?  I opened the email on multiple devices and had the same result.  I would provide a the url of the forms but they are live and I had to adjust them by creating a link to the Google Map instead.  But I would prefer to embed the map directly in the email if possible. 

As far as I know, the regular map embed code will not work in emails.  It should work using the maps API code:
