Take the coordinates from the point you want at the bottom right of the screen, send them in the email and the recipient then copies and pastes them into the Fly to/Search bar in Google Earth. Just be aware that moving the cursor a single pixel changes the coordinates so hover over your point and take them without moving your mouse.
You don't need to type the degree (°) symbol and can just leave a space instead, e.g. 40°44'54.36"N 73°59'08.32"W and 40 44'54.36"N 73 59'08.32"W should work the same and put you directly over the Empire State Building.
