This bothers me too. I don't like social media, and I do agree that they might be affecting people's careers and personal lives to some extend, but I wouldn't like to work in a company that creates such a tight bubble around such a very specifc topic.

I would also expect that a company that does "email campaigns with high conversions achieved through dynamic content such as images" would benefit from having people who at least understand social media which I assume is a large part of their user base.
