I'm an invite dealer, and nope, no scripts work. But when doing it by hand, you have to select EXACTLY 49 people, (at max) send, then repeat. Anymore, and they won't be invited. This is how I've been doing business- and you have nooooooooooooo idea how much notebook paper I go through with a 5k friend base!!!!!!! hahaha. (you have to keep track on smaller orders *rolls eyes*)
