If the email was forged I would expect more occurences than a single letter. This may simply be an artifact of either compression or the font renderer.

There is also a lack of google employees in this thread coming forward to confirm it's a fake.

In the screenshot you can clearly see they blanked out the email, subtle changes in the image may have resulted from this blanking process (for example if resolution has been changed, which I suspect is the case)
