Friends,
SumOfUs, a non-profit organization that I am a member of, just won an incredible campaign to save the whales at SeaWorld. I really want you to join them too cause I know you love whales and want to hold corporations accountable.
It's free to join, and you will get some interesting emails from them a few times a week about what you can do to take on corporations that are misbehaving! You can unsubscribe from them at any time.
