As a new customer of Accuzip, I just wanted to thank you for all of Accuzip’s help and patience with us in preparing this job so well. Our particular thanks to your technicians for multiple support calls and emails with our elementary questions while we learned on-the-job. Frankly, none of us had any experience with postal regulations or mail list technology, so we are especially grateful to have had them as a resource. Please tell them how much we appreciate their help!
