About the program

What is Every Door Direct Mail?

Every Door Direct Mail (EDDM) in San Antonio, TX is a USPS marketing program that delivers printed mailers to every address on selected carrier routes — no mailing list, postage permit, or customer data required.

Every Door Direct Mail (EDDM) is a USPS marketing program that lets any business — large or small — deliver mail to every address along a carrier route in San Antonio, without a mailing list, a bulk mail permit, or any customer data.

You select the San Antonio ZIP codes and carrier routes you want to reach, and USPS delivers to every residential and business address on those routes. EDDM postage is well below standard first-class rates, which makes it a cost-effective way to cover San Antonio neighborhoods with your offer.

With EDDM2GO Full Service, we print your mailers, sort them by carrier route, and deliver them to USPS on your behalf. You go from artwork to San Antonio mailboxes without leaving your desk.
