FB Like button in emails?

Question

Does the FB Like button work in email newsletters? Or will this only be used for a website?

A friend was asking me if you can put these in an email, and like the email (putting any URL in of course) will it work correctly as it would on a website? Would the information be updated if Person A opened email, liked the email, then Person B opened up the same email on another system will they see the increase in the total number of people liking it?

Answer 1

No.

Non-FBML like buttons are implemented via iframes, and as such won't work in emails since there's not a self-respecting email client in the world that will render an iframe in an HTML email.
