Well, thanks for all your great replies. I didn't even think about how it might come off differently to others.
In the end, though, within an hour of sending me that email, the boss took that duty out of my hands. Kind of. Now it's split between me and the salespeople, with them having the ones most likely to actually garner a response (system wouldn't let them finish application) and me with the ones less likely (they walked away and left the application process).
Oh well. Shuffling of duties seems to be a weekly job around here.
