For profitable real estate agents, there is nothing more irritating or possibly damaging than violating the countrywide Do Not Call Registry. This directory of people who have explicitly opted out of telephone contact from marketers was developed expressly to help people evade telemarketing calls, and much like the CanSpam act, it has done its job moderately well. Nonetheless, for small business people such as REALTORS, and real estate brokers, persistently inspection this registry previous to making a phone call costs time, capital and resources that are in rare supply.
