How to Start a 9×12 EDDM Postcard Agency (With Free Template Examples)

If you’ve been searching for a low-cost way to start a profitable local marketing business, the 9×12 EDDM postcard agency system might be exactly what you need.

A 9×12 postcard is a large, Every Door Direct Mail (EDDM)-approved card that features multiple local business ads, typically 12 or more, on one shared mailer. This system is known as co-op advertising, and it helps small businesses get affordable exposure while you, the agency owner, earn income from each ad spot sold.

In this post, we’ll explore how the 9×12 postcard system works, how to design your postcard layouts, and how to use our editable Canva and website templates to launch your own co-op advertising agency with ease.

What Is a 9×12 Postcard and How Does It Work?

A 9×12 postcard is a large-format mailer approved by USPS for EDDM (Every Door Direct Mail) campaigns. Instead of one business paying the full mailing cost, several businesses share the space, and the cost.

As a 9×12 agency owner, you organize the postcard, sell ad spots to local businesses, and handle printing and mailing. Businesses love it because they get targeted local reach for a fraction of the price of solo mailers.

It’s a proven co-op advertising model that works perfectly for small towns, neighborhoods, or local service areas.

Why the 9×12 Postcard System Works

The 9×12 EDDM model is powerful because it combines:

• High visibility – Every mailbox in a chosen route gets your postcard.
• Low cost – Each advertiser only pays for a fraction of the mailing.
• Community connection – It promotes local businesses together.

It’s one of the most sustainable, low-risk marketing agency models out there.
