What Is a Lettershop?

What is a lettershop?

A lettershop, sometimes called a mail house, turns printed components into finished mail. Typical work includes folding, inserting, matching, addressing, tabbing, sorting, documentation, and tray preparation. A full-service print and mail plant keeps lettershop work on the same schedule as press and data processing.

A lettershop (sometimes called a mail house) is the operation that turns printed components into mailable pieces: inserting letters into envelopes, addressing, tabbing, sorting, and preparing trays for the USPS.

Lettershop vs. printer

Some plants only print and others only mail. A full-service partner does both so the schedule does not break between facilities. DIS Direct runs press and lettershop in the same plant.

When you need a lettershop

Use a lettershop when the job includes multipacks, matched mailings, reply devices, or regulated content that needs controlled handling.

What the lettershop hands to USPS

Finished pieces still have to meet Domestic Mail Manual preparation standards for trays, bundles, documentation, and entry. The lettershop completes those steps before the mail reaches USPS.
