Being from Boston, and a little more direct than the rest of the world, gave me the ability to use this one.
When they say, “Send me information,” you say, “I’m happy to send you information. In my experience, most people ask for information for two reasons: 1) they are actually interested and are in the market for our services, which will lead to a follow-up meeting, and 2) they’re just trying to be polite and get me off the phone. Which one are you?”
I usually get a long pause, and one of three things happens: 1) they hang up on me immediately; 2) they say they’re interested and then I try to just schedule the meeting instead of sending them info; 3) they admit they were just trying to be nice, which is fine with me and it usually strikes up a nice conversation where I can ask for a referral or something.
At the end of the day, just make sure you never send information without getting something tangible in return.
