I have done a good amount of research and have found several "solutions" such as the static maps API and simply sending a link to a Gmap. However is there really no way to actually send someone a Google Map?
Well your own research shows that most mail clients don't do iFrames, so what do you think can be done?
This is on purpose by the way. iFrames and JavaScript are security risks that mail services don't want to deal with.
Your best bet is to get a static image of the map and embed it as an image in an HTML email. Put a hyperlink on it to the "full" map on Google Maps.
To do this manually in Gmail:
href
of the anchor in the section "Map with link to Google Maps"
