Which email address associated with Google Analytics tracking ID
I have a client whose Analytics tracking ID is already installed on their website. Now that we are about to launch a major marketing campaign for them, we need to be able to access Analytics in order to compare the old data with new.
So we have the tracking ID (UA-66573332-1), but the client can't figure out which of her multiple Google accounts were used to create it. She's given us the log-ins she has, but none of them seem to work.
How can we find out which Google account was used to create the Analytics ID?
