Has anybody had any success, or would recommend a query letter "blast" service such as "Smart Girls" or "Screenplay writers connection"?
I'm starting to send queries on a new spec and am not looking forward to the time consuming job of researching and sending out letters. I have been taught to make each query letter personal; i.e. find something to connect with them in the first sentence, but I could cover so many more sources by hiring one of these services to spit out thousands of letters on my behalf.
Anyone ever used one of these services with any success? Or should I just keep plugging away at trying to make each letter a personal experience?
