Nonprofit bulk mail

This page was last edited on 16 July 2019, at 23:52.

In the United States, nonprofit organizations are able to save significantly in mailing costs if properly planned in advance, using a category of mail called nonprofit bulk mail.

The largest in-house bulk mail project we handled consisted of 25,000 self-mailer pieces that we put together with the help of 30 volunteers over a week.

Nonprofit bulk mail is not a postage discount for single letter mailing - it only applies when mail is sent in bulk - 250 or more pieces of mail per geographic unit as defined by the United States Postal Service.

The below document is a work in progress that describes nonprofit bulk mail. Smaller scale organizations may try to produce nonprofit bulk mail in-house - which requires meeting a wide range of regulations established by the USPS - dimensions and design of mail piece, packaging and sorting of mailpieces, delivery and payment standards. The organization that initially developed this documentation now relies on mailing vendor companies to handle and comply with regulations.
