List Creation and Verification Your customer and marketing records are extremely valuable to your business but are, as you have no doubt discovered, extremely difficult to maintain at an effective level. The average list degenerates by 5% per month compound and that can mean misdirected communications and potential loss of existing and new business. Our list cleaning and verification services are designed to keep your lists totally credible by ensuring regular updating by skilled operators who know there are four ways to spell Smith, who know the difference between Ltd and Plc and who know how to differentiate between an e-mail address and a web address. But the most pleasant surprise will be the low cost involved in keeping your lists credible and your clients and potential clients happy.
