What is a Mail House?

Is a mail house a super-secret place built by crafty marketing engineers requiring strict security clearance to gain access? Sounds good, but no.

The term “mail house” was first introduced in 1956 by the Heidelberg News Magazine and it’s an expression that is now used for mail, print, and postage industries.

More commonly called a “letter shop” or “direct mail services company”. A mail house is simply another way of referring to a company that prepares direct mail for submitting to the United States Post Office (USPS) to get lower postage rates.

Some mail houses specialize in specific direct mail niches like postcards. Some are broader and laser print variable data letters to insert, or stuff, into envelopes. And others are full service all the way to fulfillment which is when the job requires a lot of labor or handwork.

Why you should use a mail house for your direct mailing campaigns

It is highly recommended to use a professional mail house when you have over 200 pieces or when you have variable data. A mail House is cost effective vs using staff or volunteers because:

  • It requires a lot of time to organize and manage a complex bulk mail campaign.
  • Printing in-house can be expensive and time-consuming.
  • A professional mail house is less likely to make errors in collation (for instance, a letter gets placed into the wrong envelope).
  • Most mail houses use sophisticated technology and sorting automation systems (that also add barcodes), allowing the mailing to qualify for reduced postage prices.
  • Mail houses use machines to fold, insert, seal, tab and sort mail. Completing all sorting by hand is hard work.
  • Mail houses own mailing permits with the USPS for sending mail at lower nonprofit rates.
