How to Sell Ads for Shared-Cost Direct Mailers (9x12 EDDM Postcards)

The Complete Guide for Local Marketing Entrepreneurs

Launching a shared-cost EDDM postcard agency is one of the most affordable and profitable local business models out there. But your success depends on one key skill: filling those ad spaces.

In this guide, you’ll learn exactly how to find and close advertisers for your 9×12 postcard mailers — even if you’re starting from scratch. Whether you’re a student, someone tired of your job, or just looking to be your own boss, these proven steps will help you get local businesses onboard quickly and confidently.

First: Know What You’re Really Selling

You’re not selling “leads.”
You’re not selling a guarantee.
You’re selling visibility — and exclusivity — to 10,000+ homes in a local area.

This isn’t an ad buried in a phone app.
It’s not a social post that disappears in 24 hours.
It’s not a billboard drivers pass at 50mph and forget.

Instead, you’re offering a giant, full-color postcard that lands right in the hands of real people in their homes — and gets saved, pinned to fridges, or passed around.

It’s more targeted than a billboard, more affordable than digital ads, and far more tangible than anything online.

🔒 How to Use Exclusivity to Close the Deal

Your mailer only features one business per industry. This is a major selling point — and your biggest leverage.

But sometimes, business owners hesitate or delay. Here’s how to follow up effectively:

Hi [Name],

just checking in to see if you’ve made a final decision.

I wanted to give you the courtesy heads-up since we only allow one [industry] on the card, and there’s been interest from others.

If I don’t hear back soon, we may need to move forward with another business in your category. Just let me know either way — thanks again!
