You provide your customer contact list and I will call, text or email each contact to confirm that the phone number, email, mailing address and billing address are valid and current. If the information is not current and the customer cannot be reached, I'll attempt web searches of publicly available databases (such as Whitepages.com) to find relevant information and attempt contact twice more before moving invalid contacts into a separate worksheet. If you like you can write a reasonable custom script and email form letter for me to use during the course of this task. Save money on printing and postage costs by ensuring that your mailers are delivered to the right people at the right time. Make sure that your phone and email marketing campaigns are performing and keep your customers loyal.
