1. What Are EDDM Postcards?

Every Door Direct Mail (or simply EDDM) is a magical program by USPS that lets you reach every single house, apartment, or business in a specific area—no mailing list required. For businesses, it’s a cost-effective way to market your products and services while avoiding the complexities of traditional direct mail campaigns.

Why choose 9x12 postcards for your campaign?

They provide plenty of space to showcase your content (think photos, bold offers, and details about your business).
Their large size ensures high visibility, making them harder to ignore or throw in the trash.
They’re versatile for all industries—from restaurants, realtors, and gyms to retail stores looking to drive insane amounts of traffic.

2. Why Is 9x12 the Ultimate Size for EDDM?

Not too big, not too small, but just right! Here’s why 9x12 postcards hit the marketing sweet spot:

Double the impact of smaller postcards, thanks to the expansive design space.
Room for attention-grabbing headlines and multiple high-quality images.
Bold visuals immediately stand out in a sea of boring, smaller mailers.
The first thing potential customers see in their mailbox? That’s your 9x12 postcard saying, “LOOK AT ME!”

Don’t get me wrong—smaller postcards work too, but 9x12 just gives you that extra edge. Plus, when paired with EDDM mailing with USPS, you’re looking at a killer combo.
