Automation letter or flat mail is mail that is 100% barcoded[1] using an Intelligent Mail™ barcode (IMb) and prepared for the Postal Service’s high-speed mail processing equipment. The Postal Service saves the cost of more labor-intensive sortation and shares the savings with you in the form of lower postage prices.

Automation prices are available for letters, postcards[2], flats (large envelopes)[3], and parcels[4]. Your business mail entry unit[5] can provide additional information and can help you decide if automation is right for you. A mailpiece design analyst[6] can help you design a mailpiece that will qualify for automation prices. A presort bureau or letter shop can help you prepare your mail to qualify for these special prices.

TIP
--Automation mailings have separate minimum quantity requirements; you cannot combine Presorted pieces and automation pieces to reach the minimum volume requirements.
