Not all presort levels are applicable to all mailings.
- Presort Accuracy Validation and Evaluation (PAVE) – this program is a process designed in cooperation with the mailing industry to evaluate presort software and determine its accuracy in sorting address files according to Domestic Mail Manual (DMM) standards.

- Presorted Standard – the postage rate for Standard Mail pieces that are part of a mailing and that meet minimum volume and preparation requirements. Many mailers choose to presort their mail because it results in lower postage. Because you’re doing some of the work, it costs the Postal Service less money to process and deliver those pieces of mail. They pass that savings on to the mailer in the form of commercial postage prices. Basically, “presorting” means grouping mail by ZIP code. All of the pieces going to the same destination get grouped into the same bundle or tray. You’ll sort to specific areas, and then work your way up to more general areas. All leftover mailpieces are combined together. Delivery time for standard mail is longer than 1st class mail. MORE INFO

- Suppress – using information on one or more lists to remove duplication of specific names before a mailing, or to eliminate those undesirable names.
- Tab (also called wafer seal) – a self-adhesive seal, usually round, that is used to close the open ends of selfmailers. The USPS requires that unenveloped letter-size mail pieces prepared for automation rate mailings must be secured (tabbed) to prevent an open edge from jamming their high-speed processing equipment. Construction of the mail piece plays an important role in determining automation compatibility. Standards for tabbing are based on basis weight of paper stock used and the location of the folded or bound edge. As an alternative to tabs or wafer seals, the open edge of the length of the mailpiece may be continuously glued or spot glued. Continuous glue or spot glue is permissible with single-sheet self-mailers and cards. Tabs can be clear with a perforation, or white (other special order colors are available). MORE INFO
