First-Class Mail letters having a number of nonmachinable attributes will probably pay a nonmachinable surcharge. Customers could be unpleasantly surprised that they need to pay additional postage whenever, including, they send a square minute card. The Postal Service charges additional postage because mailpieces that are rigid, square, or abnormally shaped, usually jam postal equipment and therefore are tough to process. This costs the Postal Service some time money—and might damage your mailpiece.
Many mailers fold sheets of paper to create letter-size pieces or updates. Folded pieces, or creased self-mailers, can help to save time and money because you’re not spending money on or filling envelopes. Collapsed self-mailers must certanly be sealed or they will be at the mercy of the nonmachinable surcharge. We recommend that you apply wafer seals or tabs to shut the open sides of creased mailpieces.
Here’s some really good suggestions about tabbing: Put the fold on base (along side it underneath the address) and secure the orifice in the top with an item of tape, a loss or a wafer seal.
