No idea, any evidence that Google uses email content do generate external profiles (vs. the user who received the message)?
If I write "Leroy Jenkins likes rushing" in an email, does Google create a persona called Leroy Jenkins, assigns a quality "likes rushing" to it and tries to match it to other data?
I always heard that user data is firewalled by default inside Google (PII data from one user isn't used on other users, unless explicitly shared).
Even on Photos Google seems to only allow you to appear as a suggestion on your contact's photos after you explicitly opt-in and explicitly selecting "which one is your face":
