The point is that you agree to let them process your email in accordance with whatever agreement they have with the recipient.
No, the point is that once an email leaves my server I am powerless to stop the recipient doing whatever they please with it, in the same way as a snail-mail letter.
That does not mean that I agree or consent to anything that is done with the message.
They might, for example, selectively edit the text to change the meaning, enlarge it and put it on a billboard (with my name underneath) endorsing the Ku Klux Klan.
I have not consented to that, or to anything else.
For the avoidance of doubt, I have not consented to my emails being read by the NSA either, by implication or otherwise, regardless of their relationship with Google Inc.
