Absolutely, whether you buy a mailing list from us or upload your own. We run each mailing list through a certification process to maximize delivery. We check to see that your addresses are properly formatted to the USPS requirements and we also check them again against the change of address records kept by the post office. You will sometimes notice on your order tracking a portion of your addresses in red, that shows where we have made a formatting change or change of address for you. We guarantee deliverability up to 92%. And yes, we offer you USPS tracking for all of your postcards in each order.
We make every effort to maximize your deliverable addresses. Please check out our
