Google allows easy access to multiple google accounts, which is very convenient in and of itself. However, it gets confusing when you are trying to send an email using a link or even the "send link" function of a browser from a third party website. In the gmail compose window that pops up in such case doesn't provide any clue as to which gmail account you'll be sending that particular email from.
Is there an easy way to tell if you are sending an email from the intended gmail account?
