Tools to automate and track the success of repetitive emails. Insteads of copying / pasting the same pitches in email, use tout and track response, opens, clicks, etc on all the different templates. $30/month for 1 user, $50 for 3, $100 for 10.
Instant, maybe free, video chat rooms. Not sure exactly what it does, could be useful. Hat tip to Chris Chirnside.
