Obama's NLRB disagreed with you. Trump's NLRB overturned their previous decision and agreed with your take. This will continue to go back-and forth as control of NLRB changes. I personally think email is equivalent to an office bulletin board. What NLRB has said about that is you simply can't be DISCRIMINATORY on non-work issues. So if you can post on a bulletin board about sponsoring you in a Charity Fun Run, then you can post about union activity. If the employer only allows work-related things, then it's fine for them to not allow union activity.
