When we receive your mailing list, we will process your list with software certified by the USPS in order to obtain the lowest possible postage rate for your mailing. (The USPS offers significant discounts for mail that has been printed with automation barcodes and prepared in presort order.) Within two days, your Project manager will fax you a postage statement. We will require a check for the full postage amount before we will mail your discs. When your discs are finished, they will be ink-jetted with your address information, and mailed within five days.
